LilacSat-2 FSK telemetry – some resets

LightSail QSL Card

LightSail still a faint signal
04:38 UTC nothing heard anymore
03:13 UTC getting weaker and weaker

01:39 UTC still a faint signal ~ 2 minutes ahead TLE

LightSail (final) decay prediction update

LightSail decay prediction update

LightSail status is unchanged. The TX is on but th team is unable to command.
LightSail spin analysis
… at least this make doppler and spin analysis easier

RF field strength plot shows ~ 8.5 deg/s (June 11 02:10 UTC)
the most recent telemetry (which is a bit old now) shows rates of
X = 7.225000 [deg/s]
Y = -0.300000 [deg/s]
Z = -0.087500 [deg/s]
7 deg/s is rather fast, but not as fast as we saw pre-deployment
LightSail is still continuously transmitting

all my nightly passes at 23:43 UTC, 01:30 UTC and 03:08 UTC
LightSail sends continously but no data
My first pass was at 2256 UTC (10 Jun) when I saw that behaviour. And the TX was on during all passes here over Europe – as yet. It’s amazing how long the batteries work…
