Hi Tom:

Do you know if TAC32 supports the Motorola method of differential GPS.  That's 
where the base station writes the data to disk and the rover writes it's data 
to disk.  The the same program post processes the data.  Not carrier phase, but 
is based on ranges and range rates to all the satellites.

The other thing I've wondered about is how did HP correct the but in the early 
sawtooth error back when SA was on?

Have Fun,

Brooke Clarke
