[aprssig] SATgates ? (again)

I've added a SATGate mode as described to the BPQ32 Igate code.
One consequence is that packets sent directly by the satellite, rather than
diigpeated through it, won't be Igated. Could this be an issue?

I'm not trying to change the APRS-IS. I'm trying to fix the satgate problem
by asking any author of IGate code to include a SATgate mode that will
ignore direct, undigipeated packets. When any authors respond with the
feature, then we will have a SATgate we can recommend for people to use.
This is a SATgate only issue and it should not be included in terrestrial
operation. Terrestrial APRS network has a different objective.
The people that we want to set up SATgates are Satellite folks first and in
far corners of the world and we want to eliminate this obscure problem in
that application by fixing it at hte SATgate..

No, I'm trying to make the APRS satellites work as a useful constellation
and to have their integration into the APRS-IS work in a consistent manner
all over the world.
It does - it treats your hypothetical "satgate" just like any other Igate.
I'm just trying to identify IGate code that has this SATgate mode so that we
can know what software to recommend for SATgate use.
There isn't any. But that's OK, since there isn't a special version of
APRS-IS stripped of deduplication running in your hypothetical "satgate"
mode to connect them to.
This is exactly the same non-problem as using APRS-IS for RF propagation
analysis. APRS-IS simply isn't designed for that, and the way it is
designed actively prevents its use in that manner.
