I havent used it but Direwolf has a mode to attempt to solve this problem.
If I remember correctly it has a satgate mode that instead of immediately
gating packets holds on to them to give the satelitte a chance to digipeat
and then prioritizes the digipeated packet. If none is heard i believe it
will still igate the original.
