Great idea, Jan - thanks!

First one I found was: [EDIT: since I found quite a few, I’ll see if I can consolidate all of them into one post over the next few minutes…]

SONATE-2 (via Exolaunch) on 145.900, 436.500, & 2266 MHz (from ITU search)
IRIS-F1 (via Exolaunch) on 2280 & 400.915 MHz (from ITU search)
CroCube on 145.000 & 436.5 MHz (from ITU search)
[** wide span suggests these may not be the exact freqs, but just a ‘round’ value used when filed]
Quantum Sentry on 401.075 MHz (from ITU search)
CUAVA-2 (via Momentus Vigoride 7) on 2259 & 400.65 MHz (from ITU search)
Djibouti-1B (via Momentus Vigoride 7) on 401.8 MHz (from ITU search)
[** same freq as the currently very successful Djibouti-1A]
GAINDESAT-1 (via Momentus Vigoride 7) on 401.8 MHz (from ITU search)
SOWA-1 (via Momentus Vigoride 7) on 2265.5 & 401.1 MHz (from ITU search)
TROOP-F2 (via Momentus Vigoride 7) on 916 & 1622.38 MHz (from ITU search)

Another participant in the Transporter-10 launch has reached out, so I have -4- additional objects.

PY4-1, PY4-2, PY4-3, & PY4-4 will be direct releases from the launch vehicle with the primary downlink being 62.5k LoRa on 915.6 MHz.

ITU also lists freqs of 1621.25 & 2402 MHz for this project. I believe that the 2402 MHz radio is primarily to be used for sat-to-sat comms between the 4 objects.

If anyone would like to contribute decodes to this project (since SatNogs stations historically aren’t setup for LoRa), check out GitHub - maholli/PY4_gs and/or https://tinygs.com/

Thanks, Scott!

More details in the SatNogs PY4 DB request: Add PY4 satellites to DB (#273) · Issues · librespacefoundation / SatNOGS Operations · GitLab

As for the other frequencies listed on ITU:

  • 2402 MHz - you’re correct, this is sat-to-sat coms (with round trip time-of-flight ranging, cool!)
  • 1621.25 MHz - iridium modem
