Dear, All.
I hope to get your help regarding our satellite STEP CubeLab-II. STEP CubeLab-II is in PVSAT and will be separated from PVSAT tomorrow afternoon about 3:00 PM (KST).
The TLE of PVSAT is as follow:
The transmitter for STEP CubeLab-II is developed by us. The specification for STEP CubeLab-II is as follow:
GMSK
437.485 MHz
9600 bps
AX.25
I hope to find our satellite based on your help.
Would you help to find the satellite tomorrow?

@hrkim I see that you use radio amateur frequency, could you link to your IARU coordination?
EDIT: The satellite has been added in DB with the temporary NORAD ID 99390. It will be available for scheduling in Network a couple of hours before the deployment.

So the UTC deployment time for STEP CUBELAB-II is 0600 utc on 29-June-2022, did I do that correctly?

Thanks for the update, I’ve scheduled observation for the first 24h. Please also you or @soletop answer to my previous question:
You should be able to schedule observations now if you have the permissions to do so.
Dear, Fredy.
TLE is updated by KARI as follow.
I will check the IARU link with Chosun univ.

Very nice downlink packets consistent with 9k6 seen on 2-minute interval 0900utc over the U.S. Doppler track matched PVSAT very well; unfortunately too weak for me to decode - not enough elevation. Good luck!

Hello, Fredy.
Thank you for your support.
Battery works well. We will check the others via TMTC operation.

@soletop is the satellite transmitting all the time or only above certain areas or only after commanding it?
STEP Cubelab-ii transmit the beacon every 60 seconds,
After 2 hours, we will command to the satellite for checking all the status over Korean penisula.

Currently commanding isn’t supported from the Network, however is in our plans.
