ISS CubeSat Deployment (2021-12-02): PearlAfricaSat-1 of Uganda, TAKA of Kyushu Institute of Technology, ZIMSAT-1 of Zimbabwe

https://twitter.com/astro_wakata/status/1598614138317594624

PearlAfricaSat-1: IARU coordination: IARU Sat Coordinator 435.375MHz CW and 4k8 GMSK AX25 and 145.825MHz APRS
TAKA: IARU coordination: IARU Sat Coordinator 435.375MHz unknown modulation, 145.825MHz APRS
ZIMSAT-1: IARU coordination: IARU Sat Coordinator 435.375MHz CW and 4k8 GMSK AX25, 145.825MHz APRS

Added in DB, scheduled in Network. Thanks @PE0SAT for the help and @cgbsat that let us know about the deployment.

To station owners, if you are going to schedule please have in mind that we use the ISS orbit, so let some observations available for ISS if needed.

This obs have some signal on 435.375MHz. (Not CW) Might be some satellite?

1804Z 40N ISS pass Em12jw. only Thybolt 1 a,d 2 signals heard down the band. No sign of these three while tracking the ISS. Good hunting all. N6RFM/5.

We’ve just received an email from the team that the satellites transmit at 437.375 MHz. Not sure if this is an error in the IARU page or an error in the setup of the satellites. Anyway I’m going to change the transmitters’ frequencies but I’ll set the transmitters as uncoordinated until we find out what’s going on.

There is no need for re-scheduling as the observations will be updated accordingly if the station frequency range allows it.

After communicating with the team, they send me the IARU coordination and it seems that it was a typo in the IARU page. So, I’m moving back the transmitter entries to coordinated.

0218Z 40SW ISS pass Em12jw. No sign of these three while tracking the ISS on 437.375. Good hunting all. N6RFM/5

Four TLE sets by space-track.org for the four satellites that have been deployed. I’m going to randomly set each of these to follow.

In my bandscan 2023-01-25 starting around 20:02 UTC I notice a strong signal which with help of the plot utilities appears to match Pearlafricasat-1 but transmitting on 437.326 MHz

Not in the list, I added it to my frequencies.txt and I think the curve is close enough.

Going to suggest this “new transmitter” now.
