[time-nuts] Missing GPS satellites

[Mike Feher]

I do not think so. If that were the case then the satellite terminals would
be considered as classified and handling would be a lot different.
Certainly, these terminals are compatible with SAASM, but of course they are
not in use. Most use simple Trimble, Brandywine, Motorola receiver boards,
even boards from our own Said Jackson of Jackson Labs, and we have about a
thousand of these in theater. Regards - Mike

Quite possible.  This countermeasure was discussed more than ten years
ago.

It is possible to turn of the civilian signals -- or to leave then on
but _jam_ them within a selected area -- without interfering with US
military use of the satellites.  A modern military does not need the C/
A code to acquire lock on a satellite.  It can acquire the encrypted P
code directly."
