Transfer FINE Time from a Fine Clock to a Warm Clock GPS Receiver

as shown in
Figure 18: Transfer FINE Time from Fine Clock to Warm Clock Receiver
2. Issue the following command to the warm clock receiver:
adjust1pps mark
The phase of the warm clock receiver clock is adjusted by the fractional measurement of the fine clock
receiver’s 1 PPS mark input event. In other words, it synchronizes the warm clock receiver’s 1 PPS to the
incoming 1 PPS of the fine clock receiver. It does not adjust the one second TOW counter or the receiver’s
week number. This procedure is used to make small corrections to the warm clock receiver’s clock.
