First Telemetry Recordings Downloaded


After establishing first bidirectional contact with UWE-3 first Telemetry recordings could be downloaded. The recordings verify the expected performance of the UWE-3 housekeeping during several full orbits. Satellite temperatures vary between +/- 30°C while battery temperatures remain positive around 5°C. Total power consumption is constant (ca 300mW) and battery state of charge doesn't fall below 80%. UWE-3 is spinning with about 0.8-1.0°/s. The figures below show two eclipse entries (panel temperatures [°C] over time [UTC]). As the observed times of eclipse entries didn't perfectly match the estimated orbit propagation we adjusted the estimated UWE-3 TLE as follows in order to achieve better tracking performance:
