[aprssig] Suggestion for APRS over Satellite

Hi All,

I've been toying around with the idea of building some equipment for extreme
remote telemetry stuff to be done over satellite.  (Similar to Bob's project
in Mongolia).

Anyhow, one of the things that would be extremely useful is if the satellite
could (occasionally) include its current orbital data in the beacon packet,
something like a condensed version of the Two Line Element and a CRC.  Using
this information, it could then power down the radio until the next useful
satellite pass.  This would drastically reduce the power requirements for a
remote site.  Also, things like asatlogger and what not could use the
information to update their pass predictions automatically.

Anyhow, just a thought. :)

Regards,

Hans Johnson
