GG receiver, however, allows you to compensate for this "discreteness error". You can force the
receiver to generate for each PPS (Timing pulse) a message containing the offset between the scheduled
PPS (Timing pulse) time and the actual pulse edge's arrival time. When the pulse edge is advanced
relative to the scheduled time, the offset is positive. When the pulse edge is delayed relative to the
scheduled time, the offset is negative. The accuracy of the measured offset is 2 ns.
