There is an App to alert you too. Lets you line up your phone to help spot it.
There are applications for your phone that will do it, too, based on your current location. It's pretty neat to get the notification, then go out and look, and...there it is.
This is the one I use, which also does Iridium satellite flares, which can be shockingly bright. One of the things I really like about it is that you can use the app to point yourself in the right direction and get a pretty good idea of where it will be when it becomes visible, including pointing a rough angle above the horizon, using the accelerometers in your phone.
ISS Detector for Android is pretty good.
It gives push notifications within a set amount of time of it being visible in your location. It also directs you where to look,and tells how visible it should be.
Bajense esta aplicación y les dice para donde carajo hay que mirar.
Justo hoy no estoy con el astrolabio encima.
Edit 18.57: foto asi nomas. Se ve re bien desde el medio de la ciudad. Mas que contaminación lumínica, cuidaría de no tener arboles/edificios que tapen.
I see it with my naked eye all the time. I have an app on my phone that alerts me 5 minutes before it's about to pass. You can also pick up the radio frequencies from a little handheld HAM radio.
EDIT: ADD APPS
ISS Detector Satellite Tracker Free
ISS Detector Pro
I use this app on android to alert me when the ISS will pass overhead and how bright it'll be. It's pretty dope seeing these things live and knowing they're in space.
Como te han dicho, hay apps: por ejemplo: https://play.google.com/store/apps/details?id=com.runar.issdetector
Con esa no sólo te dice cuándo se ve, sino que te muestra un radar con la dirección y la altitud. También te da información de cuándo ver otros objetos.
La IIS no es que "hoy sea visible"; se ve casi todas las semanas, varios días a la semana. A veces se ve mejor, a veces peor, a veces no se distingue por las luces.
Muy buena tu iniciativa!
Thought I'd look it up:
Found this intellectual in the reviews giving a one star because they don't understand physics: https://i.imgur.com/vpLXIsi.png
This app will notify you when ISS (as well as other satellites) is about to cross the sky in your area as well as help you track it in the sky.
You can download stellarium (it's free on PC and mac) to see the positions of pretty much everything.
Also, if you would like to see the international space station, you can download ISS detector on your phone
Have fun out there :)
Edit: some links
You've never seen the ISS in the night sky??
If not, grab one of the many ISS tracker apps and look up at the sky when and where it tells you. It's a fast bright moving spot that usually visible for about 1-10min. There are lots of other ones visible if you look at the right time and direction.
I use this one: https://play.google.com/store/apps/details?id=com.runar.issdetector
I prefer the ISS Detector, Android linked, also on Apple Store. It can track multiple objects (e.g. planets, satellites, the ISS, comets, etc (paid upgrade for some of them)) and has Augmented Reality sighting using the camera, so it's very handy to mount on a handheld antenna and use it to aim at the satellite while the sat is moving. It also gives you a prospective plot of where the satellite will rise, set, and it's azimuth, as well as projected times for each.
The ISS Detector app for Android is amazing, got the alert, sky chart shows exactly where it is and when you will see it.
Sure it's ISS Detector Once you install it, there are filters you can purchase, they aren't expensive, and are worth it. They allow filtering and tracking various satellites. The one you'll want is Amateur Radio Satellites. However I just bought the "combo package" which gives them all to you and no ads.
I think it was a couple of bucks, but it's worked flawlessly. You can set up alerts for passes that are over a certain elevation.
ISS app is what i use
GET THE PRO VERSION
havent found a free app thats has the same functionality
Remember it is moving around 8km per second, and the visibility depends how long it's reflecting sun rays, what time it is, what season it is etc. I'm sure there are apps that you can use to track it.
EDIT: like perhaps this app: https://play.google.com/store/apps/details?id=com.runar.issdetector
There are phone apps that help to see it too - I use this one (Android) but there are plenty of others.
Once I saw it fly over followed by a fainter dot. Turns out it was a Dragon capsule doing a rendezvous manoeuvre (incidentally the first one where the booster was successfully recovered). Magical.
FYI - You can easily see the ISS with the naked eye. You just need to know when and where to look. There's an app for Android called ISS Detector.
If you have an android phone I'd recommend "ISS detector", it shows iridum flares as well as the ISS. In the paid version at least, it shows planets and other objects as well.
The ISS Detector is a wonderful app which lets you keep track of its location
and you can set it so that it alerts you of any overcoming passes.
I greatly recommend checking it out to those interested!
Sure there is! You can point your phone up in the sky and aim for it.
I've seen ISS plenty of times. Usually viewable daily. Sometimes twice in a night. I use this app. It even shows you what direction to look in.
There is an app called "ISS Detector" that will give you notifications whenever it does a flyover. It also tracks the Starlink satellite, Chinese space station and several other satellites. I highly recommend the app, my 10 year old is always down to go look at any of the "fly-bys". You can also do an upgrade to have it track and give notifications for different planets in our solar system.
On my PC, I really like David Taylor's WXTrack. But in this instance I used an app on my (Android) phone called ISS Detector. I purchased the extensions (IAP) and set it for the NOAA sats and Meteor. It's a really cool app, and back when they were a thing, even calculated Iridium Flares. You can get it here: https://play.google.com/store/apps/details?id=com.runar.issdetector
I highly, highly recommend the ISS Detector app:
It will give you times and notifications for flybys of the ISS as well as any other stations/satellites up there, and was also giving iridium flares for a while - not to mention that you can point your phone at the sky to get the exact location of where the sighting will be. It's free, but completely worth buying the pro edition. I've seen the ISS so many times that it's basically mundane at this point.
I've been using this one for a while now. You have to pay $2.50 to see more satellites but you also get notifications and all the info you need for the pass all in one place. Totally worth it in my opinion. Plus if you have google opinion rewards you can get it for free like I did.
If you have an android phone, I like to use an app called iss detector satellite tractor. It'll show you when various satellites fly over including ISS.
ISS detector satellite tractor
You can even see her with your own eyes.
This is a great app to get notified when she will be visible in your location.
Seeing the ISS is easy, that's a satellite. When using my telescope, it's hard not to notice dim satellites passing through the field of view from time to time. The older-style Iridium satellites are being phased out, so their flares are less common, but I've seen those.
There are apps available to alert you when the ISS, or other particularly visible satellites, will be passing into your view. I use ISS Detector.
As an aside - this app on Android - https://play.google.com/store/apps/details?id=com.runar.issdetector - is great for this sort of stuff. Has a semi-augmented reality thingo to help you look in the right direction too. Not sure if it's on iOS though.
Don't know about this launch but you can check this site that shows you when starlink satellites are moving overhead and you can get apps that show when the ISS is visible. I use this one. It's fairly late when they're visible though.
I like ISS Detector on Android. Can give you alerts for spotting the ISS, Tiangong 2, and Iridium flares.
There is an app for android devices that is called ISS tracker. It has a lot of the amateur radio satellites along with the international space station.
I use it and it has worked very well. You have to pay 1$ to add the amateur radio satellites, but to me it was worth it. Plus it's only a dollar...
Hope this helps.
ISS Detector is a nice app, you can use it to predict when ISS and Iridium satellites will be visible from your location
I've seen the ISS many times and it was always very bright. I used ISS Detector which also tells you the magnitude of each passover. I'll keep an eye out next time. It's full moon so it would be a good oportunity, if the skies are clear.
Thanks again, I'll keep you updated with my findings :)
Hmm, that's almost three months. Half way into its lifespan. The key is to catch it and hour or so after sunset, when it is still in the sun. I saw the ISS in the florida keys once like that, it truly blew my mind. WAY brighter than anything besides the moon.
I used this app to get notified of that: https://play.google.com/store/apps/details?id=com.runar.issdetector&hl=en
iOS equivalent: https://itunes.apple.com/us/app/iss-spotter/id523486350?mt=8
There's a cool app that tell you when it's overhead and it's intensity.
It shows what the path in the sky will be, and then real time tracking when it's visible.
A few too many clouds for me.
Still, it doesn't have to pass over Minnesota to be visible from Minnesota just as long as it's fairly nearby when the Sun has dipped below the horizon for the viewer but not yet for the station itself (if at dusk).
I use ISS Detector to get advance warning of it.
I use this ( for Android ). Saw it fly over last night, it's beautiful. Perfectly visible even in urban areas, usually.
I know you're asking for books, and others will provide those, but I like to recommend a few free Android apps for newbies to get started on stargazing (without a telescope).
Well, it's hundreds of miles away from you.
If you want to see more than a point of light, use this app to find out when the ISS will pass over your area, and head to an open area with a pair of binoculars or a basic telescope. You should be able to make out the shape, but it will undoubtedly be rough and blurry.
Just building on what /u/Dannei said, there's actually an app that tells you where ISS is at any given moment so you can find it with your smart phone:
I use ISS Tracker found here: https://play.google.com/store/apps/details?id=com.runar.issdetector
There is also a Pro version that removes ads and enables some extensions, but so far the free version has worked great for me.
Ako vas ima još koji želite ili uslikati ili pogledati ISS prelet, za android uređaje ima aplikacija ISS Detector Satellite Tracker.
Pomoću kompasa u mobitelu vam pokazuje lokaciju i visinu na kojoj će se pojaviti postaja, zvukovna obavijest prije, itd.
Ovo su moji pokušaji, imao sam tronožac za fotoaparat a blenda je bila na najduljem vremenu kojim raspolaže aparat (mislim oko 15 sekundi).
It varies from dimly visible moving across an edge of the sky to clear and bright when soaring overhead - depends on the angle of the sun and position in the sky. As it orbits over 15 times a day it's just a matter of time before you get a really good sighting at any particular location. Last night was nearly directly above so it was more than twice as bright as the brightest star in our sky. I use the ISS Detector app to alert me.
I use the Android app "ISS Detector", (links: free, paid) which gives exact positioning in real time as well as local schedules and alerts, showing magnitude, angles, etc. It also does the same for other visible satellites and planets. Highly recommended.
NASA haven't updated their Spot The Station data for Dragon. Is there an alternative site I can use to see when Dragon is visible?
I normally use the ISS Detector app for ISS and Iridium, but unfortunately it doesn't include Dragon.
No es lo mismo tiempo y pasadas?
BTW: ISS Detector
Hasta ahora no pude verla pasar sobre Buenos Aires, solo los satélites iridium.
Also, there is an Android application, showing position of the ISS in realtime, named ISS Detector.
And it shows some other visible objects too; if you pay the pro version.
Yesterday I exprienced my second observation, thanks to this app. And it was awesome!
Hola como vi que les despertó la curiosidad sobre qué objeto estaban viendo y la fascinación que eso produjo aquí les traigo una aplicación y una página web que les ayudara a identificar qué objeto están viendo esta app se llama iss detector utiliza el sensor geomagnético y el giroscopio del celular para ubicarse en el espacio y así dar la ubicación exacta del objeto y es fácil de manejar muestra las ubicaciones de la estación espacial internacional y los satélites starlink y de mas objetos y también muestra los próximos pasos de objetos en la zona que se encuentren ubicados es indispensable que tenga los sensores geomagnético y el giroscopio o si no no funcionara, la otra es una página web llamada Heaven Above donde pondrán tener mapas estelares con toda la información del cielo como las estrellas y las constelaciones y todos los objetos que cruzaran y la dirección por donde salen, su punto más alto y por donde se ocultan en el cielo y también la magnitud de su brillo osea cuanto es lo mas intenso que brillan entre un número más negativo osea como -8 significa que es muy brillante y también podrán poner la ubicación donde se encuentran en la parte superior derecha asi la pagina les dará una ubicación mas precisa del objeto que o evento que quieran ver la pagina no solo tiene información sobre satélites artificiales si no también sobre eventos astronomicos espero que las disfruten ;)
I misread your comment as you thought YOU might be asleep when they came over, so I was going to send you this tracking app, but re read after I got the link and took it to mean you couldn't hear anything from the ISS. But it's in my clipboard, so here you go.
To hopefully help with your sanity check on if things are working or not, amsat lets you post the status of satellites, including the ISS, so you can see if others have had success or failures.
can easily see exact position of starlinks or the ISS or thousand other orbiting objects even Halleys distant extrasolar identification with hundreds of free phone apps https://play.google.com/store/apps/details?id=com.runar.issdetector&hl=en_US&gl=US https://play.google.com/store/apps/details?id=com.vitotechnology.StarWalk2Free&hl=en_US&gl=US
you will know where exactly to look, and exactly what you are looking at
Clearly this isn’t as cool as the close-up pictures in front of the sun or moon people post, and it's just a little white dot, but it blows my mind that a $100 doorbell camera can pick up a manmade object 254 miles away moving at 17k mph.
I use the ISS Detector app to see when ISS will be visible from my house. It was a little chilly that day and I didn’t feel like going outside, so I looked out my front door window and sure enough there it was. Afterwards it occurred to me that my doorbell camera might have picked it up, and sure enough it did!
For those who haven’t seen it in the sky, it basically looks like a star moving at about the speed of a plane. It took about 3 minutes to span the horizon, so I sped it up about 20x for my post, but here is the full clip at normal speed (it’s a little hard to notice until it gets to the middle). The video doesn’t show it once it gets behind the trees on the right, so that’s why the video stops a bit short. Enjoy!
I used the iss detector app on android to sight the iss before wenano, and collect since. Works a treat, and I think you can adjust it for visibility.
This is an excellent app on Android:
It has push notifications if it's going to be overhead, shows brightness so you can tell if you will see it or not. It does this cool AR thing where if you point the phone at the sky it will show you exactly where to look and when. It also works on all kinds of other things not just the iss.
Not the dev, just think it's a really awesome app.
I use the ISS Detector app on Android. Gives notifications for the ISS, Starlink and various other things. Uses AR to help you spot where it will rise and the track. Really good.
It is not visible every night. Usually happens for a week then moves out of view for 3-4 weeks. But it is in view for the next while. It is pretty cool when it does go zipping by at almost 8km/s
Recomendo a todos instalarem o tracker da ISS pra ver ela passando no finzinho da tarde.
Toda vez que ela fica visível na região onde estou, faço questão de parar pra ver.
I'm a big fan of the ISS Detector app for Android. Can send notifications for events like ISS flyovers, Iridium flares, and has a plugin for Starlink. Mostly I like it because it includes a tool to help you actually spot the objects in the sky.
I use ISS Detector on Android https://play.google.com/store/apps/details?id=com.runar.issdetector
It's pretty easy to use and flags the best passes with an orange marker. I would also recommend selecting both Starlink 6 (Leader and Trailer) within Famous Objects. Yes it did launch last week but the 60 satellites are still closely grouped in lower orbit.
I used the ISS detector app yesterday. Its a paid feature to also see startling (and other satellites) it pretty accurate. another pass tomorrow
With the decrease in air pollution, you can see International Space Station with naked eyes. I saw the ISS today.
App will notify you when you can see the ISS
I mean you put forth the argument that it does not exist, therefore it is your job to prove your own argument.
That aside, I suggest downloading the ISS detector app (https://play.google.com/store/apps/details?id=com.runar.issdetector) and going out every single day and watching it pass by overhead. Depending on where you are it may be difficult to see some days. As it passed by, be sure to give Andrew Morgan, Alexander Skortsov, Luca Parmitano and others a wave as they pass by overhead. I'm sure they'd love to hear from you.
Get this app (it's free) and use it to spot an Iridium flare, it's pretty accurate:
Compare that to the other flashes you have seen
I'm using ISS Detector, you add Starlink as a satellite. Stellarium is also good.
If you have a smartphone, the ISS Detector app will help you out with space station sightings and Iridium flares if you tell it your location.
I am sure iPhone users have a similar option.
The Android app ISS Detector is awesome for tracking when these occur and shows you where to look in the sky to see it.
If you're on android theres also iss satellite detector . It shows alot of other things in relation to where you are it's just some of them we have a harder time seeing because of light pollution
As far as notifications when objects are visible, the app I use to track the ISS does this for planets, iridium flares, comets, and some other satellites. But it only notifies for planets if you have the pro version. ISS Detector and ISS Detector Pro. I am still playing around with sky map apps to see which one I like best, so I can't help you much there yet.
Your VX-8DR has an APRS modem in it; have you tried listening for APRS beacons?
And, if on VFO B, you can transmit APRS beacons too, getting yourself reported on the internet if your beacon is rx'd by an I-gate; it is not hard to set up; do you have the GPS module for it? Email can be sent and received via APRS. I don't know where you are exactly, but, I'd be surprised if there was not an APRS I-gate near you somewhere. You can track individual radios via the APRS map - maybe even call them as they are driving near you (e.g., https://aprs.fi/#!mt=roadmap&z=11&call=a%2FN3FYD-9&timerange=3600&tail=1800). Zoom in on your area and see what's going on...
The local repeater here in my town is pretty dead too, save for the weekly net; but, if someone calls out, he will usually get a reply from someone; and, my friend and I use it all the time when we go camping.
You can also use either of those radios for satellites - I can pick those up all the time too. This app on my phone helps to aim the radio for satellites: https://play.google.com/store/apps/details?id=com.runar.issdetector&hl=en
I started with a 2m HT; but, HF is where the action is; I have an ft-817 for that.
I paid a couple of bucks for the app "ISS detector" that despite its name also does Iridium flares and a few other things quite well.
It has a pretty decent interface that will show you what's coming up for your location for the next few days, and if you have it open for a sighting it will tell you were in the sky it's going to be, what path it's taking, when it rises and sets, and does a little beep countdown for the actual flare. Money extremely well spent.
Fake edit: https://play.google.com/store/apps/details?id=com.runar.issdetector&hl=en
> “Look up! Do you see any one of those mothafuckas?”
Well, actually yes. If you know when to look. And there are apps for that ;)
Yea i think, different companies have different naming conventions.
This app is brilliant once you pay £3 to unlock the extra satellites
worth looking into to track your favs Noaa, M2 etc
Io ho scaricato da un mese circa ISS detector
(mi sembra un attimo migliore almeno come design) e la guardo più o meno ogni sera se le condizioni meteo lo permettono.
Il post è un pò unlucky come timing visto che il prossimo passaggio per l' Italia sarà il 30 agosto alle 6:30 ( e a meno che non sia buio pesto non si vede), due settimane fa passava ogni sera in un range dalle 21 alle 23.
Ora ha una traiettoria che manca completamente l' Italia
EDIT: Io sono in Sardegna ma credo non si veda da tutta l' Italia, inserite la vostra posizione nell' app e vedete che vi dice
I use this one: ISS Detector, which does more than just the ISS - it also tells you when and where you can see flashes from Iridium satellites, and even shows what planets are visible. I think some of these are from paid plugins, but I don't think it costs much to add them.
There's a sky map built-in showing where exactly to look, and alarms and so on you can set to remind you to go outside.
Maybe there are others equally good or better, but this one seems to do the job for me.
is a great free one for Android, can setup alerts before potential sightings.
I know you can get something similar for iOS.
Keep in mind most orbits, even at night, aren't visable or at least aren't visable for more than a few seconds. Some will also be too low on the horizon and your view will be blocked by trees, buildings, etc. Or they will be very dim.
Look for the orbits that will be high up in the sky. Magnatude is important as well, lower means brighter. So if you're on the app and see an upcoming sighting that night for something like 70° with a magnatude of -5 that's visable for 60 seconds you're gonna see a really awesome passing, assuming it's not cloudy.
There's much more you can do as a noob!
There are free satellite tracking apps you can download, which alert you when satellites are going to pass over your location & where to look in the sky. Last night I watched the ISS pass overhead. It was very clearly visible for several minutes, even with the naked eye just after sunset!
There are also free planetarium/sky map apps which you can use to pick out Mars/Venus in the sky & get something interesting to point your telescope at
If you are interested, there's an android app for locating ISS.
It has info on next sighting and also has option for notification just before the sighting.
Most likely the ISS. I was actually watching it last night exactly at 7:32:01 pm to 7:36:10. It came from NW and passed directly overhead from where I live and headed SE. If any of you are interested in seeing the ISS download ISS Detector for android. Sorry Apple users I don't know what app works.
Tell your principal. This guy shouldn't be teaching.
As for it "existing", of course it does.
You can track it with this app: https://play.google.com/store/apps/details?id=com.runar.issdetector&hl=en
People frequently take pictures of it from their telescopes: http://i.ytimg.com/vi/1CmpGQJzprc/hqdefault.jpg
I use a free android app which works fine for me and has the option to ping a notification Google Play link There's a premium version too but I've found the basic version fine for my needs (unless there's a "remove inconveniently timed cloud cover" option I am not aware of
There's also ISS detector, wich provides a live compass with heading and inclinations indicators. Makes spotting the ISS child's play. Also has payware addons for comets, iridium flares, planets and other stuff.
Satellite flare is a possibility.
With the help of ISS detector for android, I've seen irridium flares that were bright enough to be seen through light cloud cover. They can go up to magnitude -8 (more negative is brighter).
Note that there is a lot of variation in brightness for this type of events, and it is highly sensitive to your exact location.
I use this for Android. You can set alarms to remind you. It has ISS and Iridium for free, but you can purchase extensions for other stuff.
Not affiliated with it, just find it useful.
Or if you have an Android device: ISS Detector. It's great for the ISS and Iridium flares (free), as well as planet finding (IAP) It's very accurate (within a second) when using it for flares and uses your device's internal gyro and compass to help you find them in the sky.
I use this one https://play.google.com/store/apps/details?id=com.runar.issdetector . Tried it twice with WiFi and it worked. I saw the ISS at the place and time it was telling me.
Επίσης υπάρχει και αυτό το app ISS Detector Satellite Tracker (Google Play link)
I guess https://play.google.com/store/apps/details?id=com.runar.issdetector&hl=en&gl=US might work, haha.
ISS Detector is pretty good, it's actively maintained and new amateur satellites are quickly added.
iss detector for android, gpredict for desktop (linux)
ISS Spotter for Android
Check out ISS detector.. It tells you where to look using the sensors on your phone.
Track ISS in real time
Very interesting to see ISS fly by live...
Finally an overcast Saturday here in inland Mendocino County! Excited for those fall/winter vibes. My new roll-up antenna arrived this week, so I took it out for some trials. After a 20 minute walk, I found a bench at the local park and we were in business. Gear:
After I got home, I found out somebody wired our local repeater to the WIN System, and I had fun chatting & listening in. Just heard a station in the UK coming through on my handheld as I was posting this, pretty mind-blowing what's possible.
PSA--If you're not a ham radio operator (yet), pick up some gear anyway! It's totally legal to listen in without a license and the prices are very reasonable. I use the ISS Detector app for tracking satellites and the ISS. The uplink/downlink frequencies are listed right in the app, so it's caveman-easy to tune in. The ARISS program onboard the ISS periodically transmits digital commemorative imagery-postcards via a mode called Slow Scan TV, and it's easy to download the images onto your phone.
Android: ISS Detector Works great!
Man, I gotta have me some SIX MINUTE windows!!!
But if it's a very clear sky, it'll be worth the 3 or 4 minute fly-bys.
The e-mail notifications are cool if you sign up for them at https://spotthestation.nasa.gov/
Even cooler: ISS Detector Android app that lets you know when fly overs will happen, and then shows you exactly where to look!
Finally, when you're watching that thing speed by at roughly 17,150 MPH, you should know how many astronauts are aboard and where they're from. Find out at http://www.howmanypeopleareinspacerightnow.com/
Right now, when you wave at the ISS as it flies over, you'll be waving at 2 US astronauts and one Russian astronaut. And the Uber driver who drove me to work last week would be able to speak with the Russian guy fluently. Such a fascinating world we live in.
You can use their skymap , it'll tell you where to look at.
I use this ISS Detector app. It shows you other satellites too
The boom of a directional antenna will point towards the target, making the elements perpendicular to the target. Generally the elements get shorter as you go down the antenna, and the end with the shortest element needs to point at the target. Take a look at this image if you're still note sure.
With some satellites (in particular small CubeSats with no attitude control) it may be necessary to rotate the antenna as these satellites usually tumble their way through space. This changes the way the signals are emitted from the satellite (look into polarisation if you want to learn more about this).
I've been using the ISS Detector app with the Amateur Radio Satellite in-app purchase for nearly a year now. It will give you pass predictions for the ISS as well as a whole host of other interesting satellites. More often than not it will also include frequency information for a satellite. As a side-note it can also tell you when the ISS is visible from your location. Another good option for satellite tracking and pass prediction is N2YO.
If you own an Android phone, you might try some Apps like ISS Detector or Satellite AR. You can set alarms and see the predicted flight path for your location. I always use these when camping with friends and it will earn you some extra geek points from anyone with even the slightest interest in space and science.
[Edit] Shameless plug: Used these to take a picture of the ISS above Coral Bay, Australia
I use this app: https://play.google.com/store/apps/details?id=com.runar.issdetector
Reminds me when I have to take a look outside.
ah e se volete vederla passare sulla vostra testa e fare ciao, potete installare questa stupenda app
Thank you, would have missed this.
I found this great app that will let you find is very easily. Has ads but free.
I'm wondering if you're only getting e-mails on the highest brightness or highest altitude passes over your area. Looking on Heavens Above for Dhaka, you should be getting multiple visible passes this month (note that the link I provided is for a single 10 day period, so you'd need to use the arrows to look ahead further).
I use an Android app called ISS Detector Satellite Tracker (Apple version) to get notifications of visible passes. Definitely worth checking out, at least to see if your e-mail frequency is accurate.
I just received a NOAA 18 HRPT pass with the ubiquitous 2.4 GHz WiFi grid parabolic everybody knows. It works good enough to get an image, but the noise is a little higher than I'd like. I haven't delved much into custom construction or antenna theory (yet) so I'm sorry I'm not much help there. Also sorry if my "answers" seem more of a rant:
A small dish is a promising choice; I don't know if it could be done with an 80cm dish, but I know it has been done with a 120cm dish. As for hand tracking the satellite, it is feasible and doable. If you hand track the satellite I recommend either a strong arm and a light-ish dish (like the WiFi grid), or a mount such as a tripod, as each pass lasts about 15 minutes from horizon to horizon. I also recommend the Android app "ISS Detector" (with the extension IAPs) as it offers a "radar" to help keep your dish pointed on target (I rest my phone on the feed pole).
The NooElec SAWBird+ GOES' passband encompasses the HRPT signal, so that would be an easy, turnkey solution if that floats your boat. Otherwise, a great channel called The Thought Emporium has two nice videos on making hairpin filters, one with photoetching and the other with a CNC machine.
A really cool YouTuber called Tysonpower has wonderful videos, tutorials, and Thingiverse files related to HRPT and helical feeds. He uses a 1.2m Offset Dish with a custom Helical feed. I highly recommend you watch his series "Road to HRPT"; it answers some of the questions you posted here. The videos are in German, but they have English subtitles available. Tysonpower also has a free HRPT decoder built in GNURadio, and links to Peter Koistra's decoders available on his TyNet Blog.
Please kindly note that these are all the result of my empirical evidence and opinions, and this is what works for me. Your mileage may vary, but that's part of the fun!

ISS Detector for Android
Got it! THANKS!
I haven't used Gpredict before, mainly stick to Orbitron.
Most of the time I use ISS Detector for Android. It has an Amateur Radio Satellite extension as an in-app purchase which contains these satellites). It also shows uplink/downlink information for most satellites (from SatNOGS database) and can give notifications of upcoming passes. There is also an option somewhere to only notify you of passes above certain a elevation.
Highly recommend this app.
Za android ima ISS detector
Na kompu možeš ovdje pratiti uživo a ESA ima isto zgodnu kartu za praćenje na kojoj se prikazuje putanja slijedećeg preleta. Zeleni krug prikazuje područje s kojeg će bit vidljiva.
The ISS station is really easy to spot with the android app ISS Detector.
This app works great: https://play.google.com/store/apps/details?id=com.runar.issdetector&hl=en
I use this app to find it. Works pretty well. https://play.google.com/store/apps/details?id=com.runar.issdetector
For those interested this app is great to spot the ISS:
For those interested, this app ROCKS:
Me sumo a tus palabras para mencionar que también está la app ISS Detector, que sirve para más boludeces aparte de la ISS.
The ISS Detector app is free and makes tracking it really easy
You can try ISS Detector: https://play.google.com/store/apps/details?id=com.runar.issdetector or https://apps.apple.com/nl/app/iss-detector/id1198597805
You need the Famous Objects Extension. There you can add the Starlink satellites.
I'm using Robot36 as well! That app, and https://play.google.com/store/apps/details?id=com.runar.issdetector for notifications about passes.
This app here! There's an iOS version as well. https://play.google.com/store/apps/details?id=com.runar.issdetector
I got you fam.
Я пользуюсь приложением МКС Детектор, но у него сотни аналогов. https://play.google.com/store/apps/details?id=com.runar.issdetector
I use this app on android - https://play.google.com/store/apps/details?id=com.runar.issdetector
It tells you when it will be visible in the sky/where to look etc.
There's an app you can get too:
Check this bad boy out:
ISS tracker gives you a notification
Here's a great app on android for finding sats and planets: https://play.google.com/store/apps/details?id=com.runar.issdetector
Link for the lazy.
Nothing quite like watching the ISS fly from the Bay of Biscay to Egypt, of an evening.
ISS Detector. Here is the google link, but probably something for Apple as well.
I use This one on my phone. Pebble set to display notifications from it.
IIS Detector on Android is great.
Steps to track and spot ISS
1. Know the time it will be passing through the sky in your location. One can use any ISS detector app or satellite tracker app for that. There are plenty of apps, but below are my recommendation because they are free.
2. The detector app gives out the following readings. Today: https://imgur.com/a/kc8156V
Magnitude - The lesser the value, the better visibility. Only visible to the naked eye if less than 0. Today it was -3.9
ISS Rise time - 5:15 AM IST (Today)
ISS Set time - 5:19 AM IST (Today)
Max Altitude - 74 degrees (Today)
Weather condition - Cloudy (Today)
Rise direction, Set direction - South to North (Today)
The direction to look out for will be given out by the transit path in the app.
3. Use an AR-assisted app that uses the camera, every few minutes to check the position of the ISS from a few minutes ahead of the rise (today from 5:10 am). I use SkyView Lite.
(There is even a native AR assistance in the Detector app, but I do not find it as intuitive and accurate. SkyView Lite also helps you identify various other astronomical bodies - planets, stars, and constellations)
4. Use can look around in the SkyView Lite app, but to be efficient, use the search bar in the sky at the top right and search for ISS. It will help you locate it.
5. ISS is supposed to raise at 5:15 AM, but it might not be visible till it reaches the altitude of 25 degrees, say 5:16 AM. Because of light pollution or haze near the horizon. Know where to look as time passes, using the SkyView Lite App.
6. In a clear sky, if you know where to look (taking the help of SkyView Lite) after you locate it, you would not need anything else, but your eyes to observe it. Maybe a camera device to record it.
7. ISS is a satellite, and hence the light we see is from its solar panels that reflect sunlight. Therefore it does not blink like a plane or twinkle like a star. It would look like a steady star that does not even slightly twinkle and keeps moving fast in the sky, whereas other stars are static. Today there were very minimal stars due to cloudy weather, but this https://imgur.com/003saXk ISS pass on last summer on a clear sky, from the same location - looks amazing.
Oui! L'application j'utilise est ISS Detector. C'est gratuit.
Aussi, durant l'été, je fais un atelier dans le Plateau pour enseignant les gens comment à voir les survols.
No need to thank me
Bajate esa app y te dice para donde mirar.
I use an app called ISS Detector, that show you the time and direction of the ISS passing by your area
Nice! I've been using this app lately: https://play.google.com/store/apps/details?id=com.runar.issdetector&utm_source=apkdot.com
I use this. Its simple and easy to use. There is an add free version too but the adds aren't intrusive.
ISS Detector - Android
This works really good
Over here in Gardena CA, saw it last night for about 5 mins. I used this app. https://play.google.com/store/apps/details?id=com.runar.issdetector
Não consigo dar nenhuma boa recomendação, lamento.
Também tenho instalada uma para a ISS - ISS Detector - que usava com mais frequência quando era possível avistar os "Iridium flares". Ainda a uso para receber as notificações de passagem da ISS.
Embora tenha a aplicação Heavens-Above instalada, costumo recorrer mais ao website.
Não tenho nenhuma app específica para os Starlink. Costumo seguir as missões (uma app muito boa para seguir lançamentos no geral - Next SpaceFlight - com respectivos streams) e depois no próprio dia, bem como nos 2, 3 dias seguintes, sigo as informações disponibilizadas no HeavensAbove.
There's a pretty good app for this:
This app tells you when and where to look if you're on Android
There is an app for that :)
ISS Detector ?
The ISS? I use an app on android called ISS Detector on android. The ufo was just by chance that I saw it
Same app on Android
If you are on Android, ISS Detector is really good, not only for the ISS but other satellites as well.
And here's a free one for android.
It's in the Famous Objects Extension in ISS Detector.
I like this one:
If you're on Android this is a good app: https://play.google.com/store/apps/details?id=com.runar.issdetector
There's an ISS finder app on both the Apple Store and Play Store is people are interested. The Pro version of the Android app will give you notifications 5-10 minutes before a pass as well as warn you of upcoming Iridium satellite flares.
There's also another pass occurring tonight.
there is a nice app for tracking the iss: https://play.google.com/store/apps/details?id=com.runar.issdetector
I use this app on android. It's simple but accurate.
Basta usare ISS Detector!
There are several websites and apps dedicated to specifically tracking the ISS. But for general satellite tracking, I like N2YO.
Here's the link to the ISS tracking page:
And here's one for Orbital-ATK's OA-7 Cygnus vehicle (note: this one will disintegrate in a few days):
And as for apps that allow you to see when the ISS is visible, I recommend this one:
Came here to suggest this, I get Iridium flare notifications almost all the time. Its pretty good.
Also, fixed the URL: https://play.google.com/store/apps/details?id=com.runar.issdetector
There actually is. Personally I use ISS-Detector (for Android) which has some pretty neat features even in the free version.
I use "ISS Detector" on Android which also has alert features for "Iridium flares" - communications satellites reflecting the sun off their solar panels to you. It's nice to be able to only allow alerts between certain hours, and require high enough angles and brightness. A note on brightness magnitude: Negative is brighter on a logarithmic scale, the brightest star is 0, full moon is -13, so if you see a -3 or -6 sighting it's going to be bright!
I also get email alerts from the official NASA site http://spotthestation.nasa.gov/
Possible android equivalent? I don't know I'll check and come back here if I remember (https://play.google.com/store/apps/details?id=com.runar.issdetector&hl=en)
Or use this app! https://play.google.com/store/apps/details?id=com.runar.issdetector
For next time:
there's an app for that ... https://play.google.com/store/apps/details?id=com.runar.issdetector&hl=en_GB
И нахуя оно надо?
