	Does anybody know if NAVSTAR is operational yet?  Were the birds to
be launched on the shuttle (in which case, I'd expect it to be several
years behind schedule) or on disposables?

Nine of the GPS satellites are now on orbit; they are numbers 1, 2, 3,
4, 6, 8, 9, 10, and 11. Sixteen are needed for full operation of the
system; eighteen are planned so that there are two on-orbit spares.

Further GPS launches are manifested on STS-45 (1/31/91: Atlantis) and
STS-48 (5/2/91: Atlantis); I don't know offhand how many birds will be
on each.  These will be the first GPS satellites deployed from the
Shuttle; the current nine went up on expendables (Titan III's, I do
believe... anyone got the straight poop on this?)
