I speak for myself here, and not the BOD or organization as a whole.
Most of them are not the masochist I seem to be with regards to -bb.
I don't think committing to build satellites that we CANNOT afford to
launch is good business, and neither do my fellow BOD members. Designing
a satellite for an unknown launcher envelope and orbit isn't very wise
either. Or would you prefer we have -two- HEOs that no amateur effort
could afford to launch? AMSAT members should understand the days of
cheap and nearly free launches to anywhere are over, especially to HEO.
ESA's past charity with the Phase 3 Ariane launches has really ruined
all reasonable expectations. I understand your frustration, but
directing it towards the BOD is not productive. Sometimes you have to
suck it up and face facts.
We currently have two new projects in development. One is a 1U cubesat
known as AMSAT-Fox. 1U cubes only generate about 2w DC orbit average,
which is not enough to run a transponder at a level of performance our
members would expect. This is why it is a single channel system at this
point of development. The radios will also be suitable for inclusion on
other cubesats, as a income source for AMSAT, and as motivation to
develop secondary amateur missions. Fox can also serve as a partial
successor to AO-51 for about 1/5th of the cost. Without even really
starting fundraising yet, we are well on our way to being able to pay
for construction and launch.
The other project includes a Mode U/V linear transponder as a possible
secondary package on a host satellite going to LEO. Sorry if that
doesn't meet your approval to be classified as a non-"grid sat". It's
the best we can afford to do in both terms of money and volunteers.
We also have a third project in cooperation with SUNY Binghamton and IBM
to develop the frame and power systems for a 3U cubesat that will
support good LEO comms missions.
I've been beating the bushes to find ways to get us back into the
business of building and FLYING satellites, along with the rest of the
Engineering Task Force. I have a spreadsheet two pages long of failed
attempts and contacts, with only a few "may happen"s. Perhaps we'll find
some path back to high orbit when we can revive Eagle, but we shouldn't
and won't twiddle our thumbs until then.
