Clear all GPS assistance data
Clear all GPS assistance details from the modem and put the modem into a coldstart
state. Data cleared includes Almanac, Ephemeris, Previous Position, Ionosphere,
and GPS time. This forces a cold start for GPS acquisition the next time a session
starts.
The command is only available when there is no active GPS session—the GPS
receiver is off and no position fix is being calculated.
This command is equivalent to !GPSCLRASSIST when all four of that command’s
parameters are set to ‘1’.
Usage:
• Execution: AT!GPSCOLDSTART
Response:
OK
Purpose: Clear the modem’s GPS details
