AST's BlueBird Launches

Again no sign of any UHF downlinks from the 3 new BlueBird sats (SpaceMobile-11/12/13) over the eastern U.S. around 0330utc 18-Aug.

Scanning the S-Band downlinks on a different computer, a downlink on 2225 MHz aligned w/ SpaceMobile-11

… and when SpaceMobile-12 was being tracked, a downlink appeared on 2235 MHz…

No S-Band activity was observed when SpaceMobile-13 was tracked.

Do any of your have a bunch of the demodulated packets from the sats you could send me? Want to try some poking around to see if I can find anything about the telem format just from looking for patterns and the such.

Were you looking for the S-Band data stream or the 2400-baud UHF packets?

Saw looking at the UHF ones since those are the only ones I have seen anyone actually recving.

There are lots of decodes from the older BlueBird sats in SatNogs, for example:

… and I had saved some payloads from a past capture that I’ll attach here!

Hm Missed that selecting Bluebird-5 in the browse observation page doesn’t show any observations. Didn’t realized the behavior of the browse observation page changed since I was last super active in 2024. (It used to start at current day and show backwards everything, I guess now it defaults to only showing the past day of obs no matter what unless you select a custom start date)

You have to alter the query.

And then you get:

Jan | PE0SAT

Like I said, didnt know that the observation browser page was changed from how it worked years ago.
