Most of you don't know since it was to be announced at Dayton, ASCENT is AMSAT's new Advanced Satellite Communications and Exploration of New Technology program, which was formed just before this opportunity came along with several team members working on the possibilities Bob is referring to, and beyond.

The lifetime of our ultimate target, a comsat at Geo (Intelsat, Inmarsat, etc) is about 15 years. We already know the SDR will survive longer than that at GEO which is a benign orbit. This is a test launch and we will live what we live and make an argument to do more by doing lots of development and experimentation. We've built some strategic relationships and I think they will pay off as in this is not our last chance but not one to be missed.
There are synergies right now like I have not seen since I started in AMSAT in earnest to have US launches, carry US satellites to orbits that serve us and worldwide. LEO, GEO are more likely. LEO is an almost overwhelming abundance. GEO is becoming accessible as hosted payload. Even HEO launches occur and we have to hope to catch a ride.
I am the most optimistic I have been since Microsat and AO40 went up. Join your local AMSAT, help support all our activities. We are on the ascent (pun intended).

In this case, we'd be limited by the lifetime of the satellite that's hosting us. A geosynchronous satellite is going to have a finite life because fuel is required for stationkeeping.
An interesting thought though: would amateurs still be able to use the satellite even after it's been moved to a graveyard orbit?

A challenge for the group:
Can AMSAT build a satellite with a design lifespan in excess of 20 years?
These launch opportunities seem to come along once every 15+ years. Unfortunately, most of our birds seem to last a much shorter time than that. What architectures and design features can we incorporate to
achieve
virtually infinite lifespan?

AMSAT is excited to announce that we have accepted an opportunity to participate in a potential rideshare as a hosted payload on a geostationary satellite planned for launch in 2017.
All,
This is excellent news.
Do we have an official name for this yet? Will it be Project Golf (that is, the next one after Fox?) or Phase IV-A (our first Phase IV
satellite),
or Eagle-2, or perhaps something else?
While I know the frequencies/bands have not yet been announced, have any decisions been made about whether the transponder (or transponders?)
will
this be all analog, digital or both? What other payloads will we have?
Does anyone know if we will have our own telemetry downlink?
