Thank you for the link but it appears to be directed to the login page - not a specific observation.

fredy · October 7, 2026, 7:19am

Fixed it…

fredy · October 7, 2026, 7:21am

Awesome! So we have received all of them!

Now the difficult job to separate them but knowing who transmits what it makes much easier.

dooyoung · October 7, 2026, 8:35am

Hello everyone, nice to meet you again.

I am responsible for the bus development and operation of SD-1 SAT, BEE-1012, and UEL-Y-Sys. Thank you for receiving signals from our satellites.

Each satellite includes its call sign in ASCII format in the beacon header. We will soon share the information needed to parse the beacon telemetry.

All three satellites are currently operating normally with beacon transmission and two-way communication available.

hyunminkim · October 7, 2026, 8:44am

Hello, this is Hyunmin Kim from the GBSAT team.

Thanks to everyone in the SatNOGS community, we were able to receive the initial beacon and check the status of the satellite!

Fortunately, the satellite appears to be operating normally with no errors, and it is currently in the detumbling phase.

We are planning to attempt our first communication pass at around 11:00 PM KST (14:00 UTC) today.

Thank you very much to everyone who received our beacon, and we really appreciate your continued support!

If you receive a GBSAT beacon, please send the reception result together with the received HEX data to:

jemin114@kaist.ac.kr

We will send you a QSL card image in return!

EU1SAT · October 7, 2026, 9:59am

GBSAT Active and Demodulated!

hyunminkim · October 7, 2026, 10:13am

Thank you for observing our satellite’s beacon!

Could you please upload the HEX data as well? We’d like to check it right away!

hyunminkim · October 7, 2026, 10:39am

@EU1SAT

Thank you, EU1SAT! Your reception report was very helpful in checking the status of GBSAT.

If you would like to receive a QSL card, please send us an email at jemin114@kaist.ac.kr.

73!

EU1SAT · October 7, 2026, 11:44am

CPSAT Active and Demodulated!

Hi Dooyoung,

2026-10-07 on pass at 11:2x UTC I’ve decoded

2026-10-07 11:2x UTC BEE-1012 + SD-1_SAT + UEL-Y-SYS - DL7NDR.zip (5.4 KB)

Do you issue QSL cards for these satellites?
I was happy about your card for BEE-1000.

Daniel, dl7ndr

dl7ndr · October 7, 2026, 12:21pm

Hi Hyunmin,

2026-10-07 on pass at 11:2x UTC I’ve decoded 1x GBSAT.

2026-10-07T11:28:57 UTC GB0SAT0 - DL7NDR.zip (19.4 KB)

Will send you an email for QSL card.

Daniel, dl7ndr

dooyoung · October 7, 2026, 12:25pm

Hi Daniel,

Thank you again for receiving our signals!

Yes, we’re planning to design a QSL card for each satellite.

Please feel free to leave me a message through the community or send me an email at rei0119@yonsei.ac.kr.

We’ll be happy to send you QSL cards for all three satellites!

11:25-11:35 UTC - GBSAT rx in Greece. Replay of recorded IQ.

Nuri nails five-satellite mission, eyes commercial future - The Korea Herald which reports that “PERSAT-02 CubeSat, failed to separate”

sv2hwm · October 7, 2026, 12:57pm

11:25-11:35 UTC - SLEDGE received with turnstile antenna + LNA/BPF, but the signal was too weak to be demodulated @ 19200 bd.

@dl7ndr @sv2hwm

Thank you both for receiving GBSAT’s signal!
Your observations have been really helpful for us in checking the satellite’s status.

We really appreciate your support! 73!

Hi Isaac,

2026-10-07 at 13:03 UTC I’ve decoded 2x CPSAT.
