Listening To the International Space Station The Cheap Way

Ғылым және технология

As a follow-up to some of my weather satellite projects, I tried my hand at listening to the ISS. Lately they've been sending down Slow Scan TV (SSTV) images, which are kind of like power point slides sent via fax tones over ham radio!
I tried a variety of old ham radio junk I have lying around, but the easiest and most reliable equipment turned out to be the cheapest! The thing that worked best for me was a ~$30 Baofeng radio with a cell phone held up to the speaker. The phone is running an app called "Robot36" which decodes the SSTV tones into an image.
(A lot of hams look down on these Baofeng radios, but mine works better than my old Yaesu or Icom 2M handhelds, and was a lot more affordable brand new!)
More info on SSTV here: amsat-uk.org/beginners/iss-sstv/
Robot36 App: play.google.com/store/apps/de...
I tried various Windows and Linux programs but didn't have much luck getting any of them to work. The only one that kind of worked was "RX-SSTV", but the image came out distorted and the user interface was clunky and confusing. The Android app does everything automatically and works with little to no user input.
I might revisit this next time there's an SSTV event, especially if I build a better antenna!

    Don’t bother to finetune for the doppler. Also, best to record the sound (you can use squelch and VOX recording, that works well) and then normalise in Audacity and then play it into a PC software (MMSSTV). A dipole will work fine in most cases but I’ve had equally good results using my normal roof antenna. I’ve typically managed to grab two, maybe two and a half images per pass, but obviously you’re limited by the length of the pass.

    Just one small hint: In Germany it is even forbidden to LISTEN to ATC transmissions. Thats why there are no German Airports on the live-ATC website. OK, there is probably no way someone will find out if you listen to ATC in your home. But listening to it while plainspotting in public without the "Flugfunkzeugnis" could get you in trouble.

    I wonder if Digital SSTV will become the new norm down the line when some of the issues are ironed out! They send "raw" image and files so it's almost lossless, but they do have a problem of being very slow and prone to getting interrupted by noises or fading signal.

    I wonder if you had more gain on your antenna to improve your SNR and maybe a more sensitive receiver would help. I noticed your signals are a little low for what have see. Note I found Baofengs and all SOIC based radios tend to be a little deaf. I found this building APRS digipeaters.

    I’ve done a fair bit with the ISS and APRS. As long as you have a radio that will do it, and a decent antenna (you need a yagi if you’re using a 5w handie) and just keep trying. High overhead passes are highest likelihood of getting a ping. Don’t worry about correcting for the doppler. I can still get it all working without correction.

    IF, in fact, this is slow scan tv, then why not get an old sstv ham unit and rebuild it to the frequencies you need? I used to do pirate sstv back in the late 60s and got the ss signals from weather satellites and also from lunar transmissions. Tried to get the russian one from their probe on venus but it was too weak to process.

    Aircraft voice radio uses AM VHF (which is kind of weird but I guess has its reasons). You need a special radio or an aircraft capable scanner, or a software-defined radio (The little USB deals I used in other videos, they're getting pretty cheap). You can also use those to track aircraft transponders directly the way flightradar does. I haven't played around with that much, I have an old Radio Shack scanner somewhere that can hear the cockpit / air traffic radio but it's usually pretty boring unless there's an emergency.

    Have a look for ADS-B. Easy to pick up with a SDR, and it’s like flight radar “local”. Don’t know if it’s still the case, but if you host a receiver 24/7 and feed it into flightradar, they’ll upgrade your account to “pro” in return.
