A great posting from Patrick. Good practical commonsense.
A non battery option has been discussed many time on the UK Amsat Midlands
net as far back as 2001.
Robert G8ATE in particular suggested that all satellites should have a
"failure mode" in which the batteries were out of circuit and the
transponder ran on solar power. AO-7 is the prime example. What about night
time operations? If the orbit is higher the Sun time for any station is
extended.
Is a compromise possible, here. A solar only transponder satellite might be
a bit radical, could it be a switchable option?
Taking up Patrick's point it could be a high power mode.
