Subject: [aprssig] RAFT first 2 passes status:
RAFT STATUS:
RAFT is operational for over 2.5 hours and telemetry shows the system
operational with battery voltages slowly charging up. The first pass showed
volts halfway through eclipse at 7.3, but the second pass showed volts
further into eclipse gaining at 7.8 volts. Full charge is 8.4 volts.
Telemetry shows we are getting a low-power shut down before the end of
eclipse since the telemetry counter is re-starting at the start of the
sunny side. We expect voltage to continue to improve and so are doing no
commanding at this point.
Temperatures were about 0 deg C on the first pass, but improving to about 2
deg C on the second pass.
Signals require a good oscar array, and we could use some Additonal
telemetry. Just send anything you get. Thanks
