10 Event Marker Input and 1PPS Output
116 5700/5800 GPS Receiver User Guide
55700 Reference
A typical printout looks like this:
UTC 93.12.21 20:21:16 56
UTC 93.12.21 20:21:17 56
UTC 93.12.21 20:21:18 56
If a and b are ??, the time is based on the receiver clock because the
receiver is not tracking satellites. The receiver clock is less accurate
than time readings extracted from satellite signals.
