Dear Shaun, If you use Geodesic receivers or some special GPS receivers and requires few ns, please use a phase stable cable and two DC bias passing attenuators (10dB etc) to antenna side and receiver side, if possible please use temperature stabilized antenna. I am using a phase stable cable a

If the two positions are fixed, say a permanent VLBI or bi-static radar installation, You can do pretty well (say < 5 ns delta between sites) with GPS-steered cesium. The long-term stability of the delta can be even better (say < 1 ns). Even with civilian one-way GPS, the cesium allows you t

[time-nuts] Synchronisation using GPS

2005-08-08 Thread Shaun Doughty
Hello, I am currently looking at GPS as a possible way of synchronising transmission/reception within a radar network. I was wondering if anyone had perhaps previously used GPS to synchronise various locations in this way (mine will likely be a couple of km apart max) and if there were any recomme
