Cool, thanks @pu4elt! I’ve fixed the title (I’ve also moved the thread under Satellite & Observations → Launches category). Now we will wait for the time of the deployment.

Satellites have been scheduled for the first 24h using the TLE sets of the previous post, the difference in the number of scheduled observations is based on the frequency, the deployment time of the satellites and the requests by satellite teams:

Satellite Observations
98654 RSP-03 380
98541 GHS-01 279
98540 STARS-Me2 310
98539 Dragonfly 271
Total 1240

Note:
Scheduling only for the first 24h as we expect the ISS TLE used for the satellites to be soon deprecated. Updated TLE will be generated for the satellites if we receive their signals.

Hi. @dl7ndr, all
It has been successfully deployed. Now the real mission begins. We’ll be monitoring it night after night to help stabilize the satellite. please countinus comunicate (support). :sweat_smile:

I also haven’t seen any signals now.

15.39 UTC Nothing :thinking:

17:05 UTC zenith pass - no signals

That’s a shame… I was watching that pass slicing right through the middle of EU and thought to myself that if ANY of these sats are transmitting, there will surely be some reports from all those stations.

2025-09-19 17:44:15 UTC = no signal

Again no signals (18:40 UTC)

Same story on both of tonight’s passes over the Eastern U.S., I’m afraid.

We see deployments with a few sats that are never heard from, but this one seems odd.

Has anyone seen comments from any of the Project Teams speculating what the issue might be here?
