I have submitted for a tlm certificate my analysis of the voice telemetry from Arissat-1 on certain orbits in September (when I was present, hi). The dates of the receptions in September are in the analysis spreadsheet.
The MET is decreasing, I think this is because the satellite comes out of eclipse and swithches on nearer the observation, as the orbit is precessing I think the analysis shows that as the MET decreases, the IHU temperature decreases, and the battery current increases (this is a lesser negative number). Put that another way, as the MET in sunlight increases, the IHU temperature increases and the circuit current decreases (greater negative number). However I don't know why the circuit reports a negative current, or even if the voice tlm is accurate. I'd be grateful for any comments. 73 de Andy G0SFJ . _______________________________________________ Sent via [email protected]. Opinions expressed are those of the author. Not an AMSAT-NA member?
