<DIV>Hi Werner,</DIV>
<DIV> </DIV>
<DIV>Did you also look at the phase differences between the 1PPS output from
each Thunderbolt?</DIV>

Simon,
<DIV> </DIV>
<DIV>when I ran 3 Trimble Thunderbolts against each other on different antennas
their GPS 10 Mhz phases driftet appr. 0,3 deg per second. So I'm not sure if
synchronisation of receivers at different locations with time stamped data would
work via Internet as phases could differ +/- 20 deg over time before turning
direction.</DIV>
