I don't think so ! Each GPS satellite do 2 Earth rotation every 24 hours. But, in a fixed point on the Earth, a receiver do not see one satellite for 12 hours ! And, the algorithm implemented in the receiver select the strongest signal from those received one time. So, the receiver locks on several satellites over a day. _______________________________________________ questions mailing list questions@lists.ntp.isc.org https://lists.ntp.isc.org/mailman/listinfo/questions
