AO-7 Emergency receiver



It seems silly to let a good and sane satellite die just because of a
battery short which I suppose could have been foreseen. What about an
emergency receiver with its own dedicated and separate solar array, say a
couple of rows of solar cells all around the circumference of the satellite
so they see the sun irrespective of orientation in space.

On command from earth, the receiver would act on a pyro-technical device -
or a relay if not too power consuming - triggering a switch that would
de-couple the shorted battery elements from the power line. And the s/c
would live happily ever after, singing to us for decades.

Is this a crazy idea or could it be done in future satellites?  The
emergency receiver could of course perform other vital tasks in addition to
the above. The problem of accidental triggering would also have to be
addressed to avoid premature de-coupling of the batteries if the switching
process is irreversible.
