3.8.1 1PPS Signal
The 1PPS signal is available in the modem. It outputs a pulse per second by default,
provided a valid GPS signal is present. If the GPS signal is blocked, the 1PPS stops.
By default the GPS is only on when requested by the application or the network. For
constant time updates, the GPS must be on at all times.
