[amsat-bb] PCsat Status

[Bob Bruninga <bruninga@xxxxxxxx>]

We are seeing some PCsat improvement.

At about 0030z on the 6th, I saw a T#56 showing battery voltages of 15.9
and 16.5 volts.  This is about 5 minutes into eclipse and represents about
1.32/1.35 volts per cell.

Checking the APRS internet feed backwards to 2314z I found a telemetry
count of T#80 captured by the ZR1CBC sategate in South Africa which
represents 80 minutes out of our 100 minute orbit and PCsat was still
running (but going to die any moment at 1.05 and 1.15 volts per cell).

This was 25 minutes through our 36 minute eclipse and the longest we have
seen so far.  Notice that we are still in maximum eclipse but on the way
out, but the real improvement is that more of our +Z face is illuminated
as the orbit precesses more into the northern sunshine and the sun moves
northward.

In another week we may be out of the woods! (for a month..)
