Howdy !
Can someone tell us how which active GPS satellites are down to no
redundancy on critical systems (bus, clocks, reaction wheels) ?
The interview with outgoing USAF Col. David Madden says he wasn't sure
there was a need to launch another IIF this year.
If launch pace continues as the IIR-M pace was, USAF will be launching
IIFs until the end of the decade.
IIIA will end up left in storage or launched ahead of the final IIFs
for early testing.
Hopefully, USAF will use this as an opportunity to keep launching IIFs
within schedule, using the excess satellites as an opportunity to
improve constellation geometry (an optimal 32 satellite constellation
would improve worst case PDOPs substantially, I would sugest having
the 4 most important orbits with 6 satellites evenly spaced and the
other 2 orbits with 4 each), one *can* dream...
Should another 4 IIFs be launched, that would make 24 fully healthy
modernized (IIR + IIR-M + IIF) satellites (considering SVN49 as a
residual or an odd ball half healthy bird and no future issues).
Hopefully the Galileo constellation will go ahead and serve as a real
competition for USAF to improve further on is performance standards.
Performance standards are far bellow what could be achieved. Enough
has been saved by slowing down new satellite launches, make GPS be
today what Galileo might be someday (sub meter accuracy 24x7)
Unfortunately the position of SVN62 tells me this won't happen
(Hopefully it's positioned there for apples to apples comparison to
SVN30/PRN30, and will be moved to a better position in a few months).
PS: I'm not trying to be an ass. But the wheels of the military don't
move with much speed, often a nudge helps... If they care they will
listen, if they don't I just hope this won't upset anybody...
Nothing in life is easy, most times we go for 99% when we can do
99.99%.
