RGPSM202

SlimGPS™ Receiver

Important Note: after the receiver gets this command the content of the GPS data RAM will be saved in the back-up

Flash upon the first position fix.

5.4.10.3 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.
