[amsat-bb] Instant Track co-visibility

Hello everybody, I was wondering if there is a way to predict the visibility of a single satellite from two or more ground stations.

I will use Instant Track, but I would like to have a suggestion for a more recent sw. It 'a pity that IT is no more updated, it would be very nice to have a port of it on linux.
