Bill,

My question was more generally about any GPSDO, but it's good to know
about the Motorola/Lucent.

What about this scenario - the GPSDO has a fixed position on initial
powerup, but then it is moved periodically or even continuously,
without updating the GPS coordinates. The distance from the original
coordinates could be anywhere from close by, to across the state.
Periodically, a new survey could be run to keep things from getting
too far out in left field.

At some point, I'll have to do some field testing, but I wanted to get
the list wisdom first.
