I think it was this thread. But the actual chip rates derive from a 10.22999999543 clock. We call it 1.023 Mhz but its not. In time-nuttery it matters. Doesn't that make the use of the signal a bit messy?
Nope. You missed the point of this off the mark is to compensate for the relativistic frequency shift that is occuring so the GPS clock at launch is at this rate, but when in orbit it will run a little faster, so this rate will match up better. Then, the remaining error is corrected for in the broadcast model so this first degree approximation will just get that decently into range.
Check ICD GPS 200D. Cheers, Magnus _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
