Joe,
The requirements, both physical and regulatory, are much more difficult than
what it takes for a LEO satellites like the FOX-series cubesats. Orbital
debris mitigation, active orbital orientation, and radiation hardening
are just
a few of the challenges that have to be met and satisfied before launch can
even be considered.
Still, it would be nice to have a duplicate of QO-100 over our skies.
It would
certainly be a game-changer. If the design plans are open, it might
reduce the
time to launch by just duplicating the QO-100 design and focus on finding a
willing host.
I've been searching around looking at the Phase 4 activities that were
going on
a few years ago. It looks like it has been quiet for a couple of
years. If I
recall, there were some things about it that unsettled me a bit. First,
was the
plan for it to be all digital, with a limit of about 100 terminals
working the
five-and-dime channel at any time. Second, the cost goal for a terminal was
to be $1000, but they had a hard time reaching $1500. Third, each
terminal would
be set up with aN ARAP (Amateur Radio Access Point), which would allow
legacy
radio to communicate through the 'radio network'. The combination of
cost (another
rich man's toy), accessibility, and regulated structure were a bit of a
turn-off
for me. If I wanted to communicate with my hand held radio via a
'virtual pipe'
to someone on the other side of the world, I'd just buy a DMR radio and
hot spot.
