For those following what was announced at the AMSAT Symposium, there are
two different ways AMSAT is working with the Universities:
(a) AMSAT-NA helps a University Satellite Program: This is the case with
UCF, AMSAT volunteers are helping a University with their satellites.
(b) A University helps the AMSAT-NA Satellite Program: This is the case
with Binghamton University, BU Students are helping build & launch AMSAT
The two ways are not mutually exclusive, each has benefits.
The BU activity was organized to help get AMSAT back on it's engineering
feet and to provide continuing assistance. We're doing that by providing
engineering assistance and manpower to help AMSAT launch more modular
design satellites ASAP. We're at 35 students right now, that number can
grow significantly next fall at AMSAT's direction. Our goal is to get an
Engineering model of the NextGen satellite bus ready for the AMSAT booth
at the Dayton Hamvention in May 2010. Engineering model says we have the
modified spaceframe with deployable wings ready, power system ready
(with mock supercaps & solar cells) and the non-flight boards installed
- basically stuffed 'n mounted on a stand for your viewing.
NextGen is an open-source spacecraft bus, it will provide a stable &
robust platform for any university to build an experiment to fit within
I would personally advocate AMSAT launching up to two or three of the
NextGen-class spacecraft in different 600-800km, sun-synchronous orbits
to provide as much worldwide coverage as possible. Given the proposed
characteristics of the NextGen spacecraft bus, there is a strong
possibility of carrying an IF Matrix Switch with L/S RF capability
instead of an experiment payload. This would provide capabilities
similar to AO-51 (V/U, V/S, L/U, L/S) but using SDX with an IF Matrix
By using Supercapacitors instead of batteries there is a very good
chance of having a significant satellite lifespan (15+ years).
All technology developed can be applied to other classes of AMSAT
spacecraft, just as NextGen is using modules from the ARISSat-class
spacecraft. I would expect that ARISSat-2 will most likely take
advantage of the power system modifications developed for NextGen.
The possibilities are endless, all it takes are more people interested
in working on a module.
