Hi Ulrich,
mind. On the other hand: If a good timing receiver has ended his site
survey it's position messages stay constant, even if you move it around.
Obviously that is not what you expect from a navigation system. Keep
navigation and timing receivers clear apart from each other. They are
of precise time and frequency measurement
Betreff: [time-nuts] 1PPS accuracy of commercial GPS receivers
Just out of idle curiosity, is there any significant
difference in 1PPS
accuracy between different GPS modules?
I've got a pair of Trimble SVeeSix CM3 boards (firmware 4.13

The receiver can use this redundant information in two ways:
a) to improve the solutions for the position
or
b) to improve the solutions for the time
but not both at the same time.
That's just bogus.
First of all, you
