4.1.2 Initialization Information ($PGRMI GARMIN
proprietary format)
The $PGRMI sentence provides information used to initialize
the sensor board set position and time used for satellite
acquisition. Receipt of this sentence by the board set
causes the software to restart the satellite acquisition
process. The GPS 30 will echo this sentence. The GPS 30
SL will echo the sentence if the data is accepted. If the data
is unreasonable then the $PGRMI sentence is sent
containing current values used in each of the fields.
