[aprssig] Satellite positions: User Statistics

[Lynn W. Deffenbaugh (Mr)]

I only quoted the statistics at the moment because I monitor them 
routinely and they really don't vary as much as you might expect.  
Install a copy of APRSIS32, attach it to a full feed (port 10152) and 
you can see the dynamics as well.  The numbers will be parentheticals in 
the View menu drop-down, especially View / Platforms and View / Transport.

Also, your target for the satellite auto-responder may be mobiles, and 
they may be the users that stand the most to benefit, but my target is 
any APRS user that has a passing curiosity and messaging capability.
