The answer is almost surely no because we will not be able to easily steer
the interlink antennas and close the link. Much more likely is a common
ground station link. This is TBD after we know we can make the minimum of
paying for the launch and get the SDR in "testable" but not final form. On
the latter we have just under two years from now, on the former we have one
year.
AMSAT-NA and VT will work this out. We are not overwhelmed by this
prospect but we are being cautious in our public statements even as we
clearly understand the excitement and joy and clamor for information.
Welcome to the new situation. We've found access to launches where we are
going to have to keep our mouths shut and our eyes open and our powder
dry. I am expecting that soon enough we will be doing things like saying
"We have acquired a launch for XXX and ooops, by the way, here are the
TLE". It is not ideal, but better than the zero significant launches since
1991!

Too achieve the vision we had for EMCOM, the ground terminal will almost
certainly have to support C4FM so as to support long haul back haul of
EMCOM from the P25 devices in the impacted disaster area. I am patient. I
view this launch as an experiment where the Americas get a facility DIRT
CHEAP that no one has provided and if we play our cards ride, this awesome
but possibly suboptimal to perfection opportunity will lead to a nearly
perfect opportunity.
Michelle has been rabble rousing for this for some time. She's right and
glad you mentioned it. We need a volunteer to work on C4FM code to make
this happen and a GREAT thing for AMSAT to do which will benefit ALL of
amateur radio and beyond.

Yes, but we will have to have a tracking antenna flown and mounted on the
truss. When you find the millions to get beyond manned space flight
hurdles, I would LOVE to do it.

Bob,
A hearty thank you to you and all the folks sitting around the table on
April 13, 2015 contemplating possibilities how to fast forward our Amateur
Radio Satellite capabilities by leaps and bounds. The FOX program has been
looking great, this is more in the unbelievable category (but we can
certainly work under these conditions...<grin>).
On the note of Radio Scouting / K2BSA - National Jamboree (as one of the
staff at that event)
...We sure kept the birds we had available busy at the K2BSA Boy Scouts of
America Jamboree in July of 2013 in West Virginia where we had more than
25,000 Scouts in attendance, and couple thousand visit our K2BSA operation
in one way or another probably more.
I'm not sure if this satellite will fly before the July 2017 National
Scouting Jamboree, but it would be great if we could showcase it, that
would be an outstanding opportunity. Else, the World Jamboree happens in
Summer 2019 at the same location I believe.
For annual Radio Scouting:
Imagine the impact for JOTA, Jamboree on the Air, where we know lots of
Scouts eventually become Amateur Radio Operators, because when we do Radio
Scouting events, we find lots of folks say, I started my interest in radio
in Scouting.
Just dreaming, Thanks for giving us the opportunity to dream, and see what
comes to fruition.
Mike
W4UOO
P.S. I knew I needed to hang on to that Primestar dish from AO-40 for the
eventual possibilities, here we are...

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?
73,
Douglas KA2UPW/5

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?
73s,
David KD5QGR

Triple modular redundancy, NASA EEE INST-002 derating, likely lot by lot
destructive testing on parts. Ability to reset quickly from radiation hits
(in GEO this is much larger of an affect than LEO), Low TID radiation
"wearout".
I'd err more towards graceful failure design than lot by lot destructive
testing.

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?

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).
