Actually, there has been a west coast control station, for exactly that
reason, for some time. However, the problem is that without being able to
keep the computer up through eclipse, everything is lost each orbit.

Hi Drew & all,
I'm not 100% sure how the software uploads take place, however I have
Would there be any benefit having one uplink station on the west coast
and another on the East coast, purely to allow the complete upload to
take place before an eclipse?
Perhaps the users of AO-51 would donate to a road-trip fund to send
one of the command stations /portable to a location of benefit to
Just trying to think outside the box :-)
good luck with the uploads,

Currently, the satellite will not retain the upload of the flight software
across eclipse. The batteries are in very poor condition. We have a few more
things to try, but with eclipses peaking around July at ~27 minutes, the
long term situation is grim. There is a brief period around November where
eclipses are as short as 16 minutes, but past that it is a long climb to 30
minutes or longer eclipses for many years. We have no expected "return to
service" date. If you have 9k6 digital capability, you can listen in on our
attempts at recovery on 435.150 on many passes over the US.
