[amsat-bb] GEO sats and the future

Just to summarize - right now, there are three serious HEO/GEO
projects in progress:

1. Phase 4A is the S/X linear transponder payload on the Qatari
Es'HailSat-2 scheduled to launch late this year. AMSAT-DL has done the
work on the amateur payload. It will be in a geostationary orbit that
is not visible to North America (26 degrees east).
2. Phase 4B is a planned C/X digital payload on a U. S. government
satellite launching in the next few years. AMSAT-NA and Virginia Tech
are involved with this. It will be in a geosynchronous, but not
geostationary orbit over the Western Hemisphere.
3. Phase 3E in a Molniya HEO orbit. AMSAT-NA and Virginia Tech are
involved with this. Transponder payloads TBD.

A global network of 3 linked geostationary satellites covering the
whole world would be pretty neat, but I think we'll need people to see
what we as a community can do with each of the two Phase 4
transponders planned right now before the support (read $$$$$) for
such a thing would be available.
