PPO: Point Positioning
$PASHS,PPO,c
Enable/disable point positioning mode, where c is either Y (enable) or N (disable).
Point positioning is an averaging algorithm that will improve the stand alone accuracy
of a static point after about 4 hours.
Example: Enable point positioning

PPS: Pulse Per Second
$PASHS,PPS,d1,f2,c3
The receiver generates PPS pulse with programmable period and offset with respect
to GPS time. The PPS set command allows the user to change the period and the
offset of the pulse, and to either synchronize the rising edge of the pulse with GPS
time, or synchronize the falling edge of the pulse with GPS time. PPS is generated by
default once every second with its rising edge synchronized to GPS time and no
offset.
The period set to 0 will disable the PPS output. Between 0 and 1, the period can be set in increments
of 0.1. Between 1 and 60, the period can be set in increments of 1.
Example: Set PPS to a period of 2 seconds, a offset of 500ms, and synchronize the
rising edge of the pulse with GPS time.
