GPS Receiver
Delete the initial position
This NMEA sentence has the same effect as the hardware input DELPOSN. It allows deleting the initial position in the
RAM portion of the MCU and triggering re-computation of the tracking set. The position will not be deleted if GPS fixes
are already being generated. This function is useful when the initial position is known to be incorrect, for example when
the receiver is powered down, put on a plane, flown 20,000 km, and then warm-started. The command is:
$PXEMSTR,SSDI*74
Important Note: after the PXEMSTR,SSDI command is sent, the receiver should make a position fix before it saves GPS
data in its back-up Flash memory
