One more comment: the GPS disciplining doesn't affect performance of parts to the 14th short term. GPS is used for long-term (>1000s or so) error correction, where it can achieve parts the 14th, but only after a day or much longer. GPS is not good enough to give you more than parts to the 8th-9th timing accuracy per second, which is already accuracy in the feet range. Parts to the 14th short term would require accuracy in the 0.00001 foot range, not possible. bye, Said In a message dated 4/23/2008 16:36:32 Pacific Daylight Time, [EMAIL PROTECTED] writes: >With the Rubidium disciplined by the GPS, >with its on-board Rubidium/Cesium oscillators updated from the ground every >orbit, you have parts in the 14th, short term.

I have some Wenzel OCXOs that hit 5E-13 for a 1 second tau. No Rb or Cs or Z3801 that I have running get that good at 1 sec tau! Over 10,000 is a different matter, however. -Brian, WA1ZMS **************Need a new ride? Check out the largest site for U.S. used car listings at AOL Autos.
