1PPS Output
The GPS receiver is in navigation mode upon power-up, with 1PPS output free running. After 3 minutes of
valid position fix and remaining under static-mode, the receiver changes to timing-mode, with 1PPS output
signal synchronized to the UTC second. The receiver will change to navigation-mode, with 1PPS output free
running, if the receiver is in motion. The 1PPS output will become synchronized to the UTC second again after
the receiver had remained in static mode for 3 minutes.
