I’ve updated the information for the satellites in the first post. Thanks to @PE0SAT for his help on gathering info. It looks like we are almost ready for the launch.

As we get closer to the launch, we are going to publish here the TLE sets for the satellites and also we are going to schedule observations in Network sharing the stations observations among the satellites.

EDIT this dataset has some calculations wrong, a new post will follow with new TLE sets.

Here are some preliminary TLE sets for this launch. NORAD IDs have been adjusted to follow the temporary ones we use in SatNOGS DB:

Scheduling in Network for the next 48h is done. Totally 1227 observations, with most of them over 10 degrees elevation, have been scheduled. However it may need some re-scheduling after having more accurate orbital data.

Launch is on hold, trying to catch the window. New TLE set will be generated after a successful launch. Observations are going to be re-scheduled as soon as we have the TLE sets in SatNOGS DB.

According to the latest updates the new launch timestamp is 2024-07-03 04:03 UTC.

Later today I’ll post again updated TLE sets.

One more update from Firefly that they will not try to launch in the new datetime announced earlier. A new window will be determined.

Unfortunately haven’t seen that early :frowning:

The satellites have been set as launched and scheduled for the first 24h with the TLE @PE0SAT posted above.

Nothing heard on 435 MHz on this pass over Minsk :frowning:

Nothing heard yet on Network observations too. However most of them were low elevation ones, so we keep tracking.

3 Likes

Given that we haven’t listened anything yet and there are some references that some of the satellites are alive, we may need to consider that the preliminary TLE sets aren’t accurate. However until someone else share anything more accurate we will continue trying with these.

We have TLE from space-track, which confirms that our preliminary TLE were very close:
