Clear specific GPS assistance data
This command clears one or more types of assistance data from the
modem. 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 !GPSCOLDSTART when all four
parameters are set to '1'.
Usage:
•
AT!GPSCLRASSIST=? returns the expected command format and
supported values.
•
AT!GPSCLRASSIST=<eph>, <alm>, <pos>, <time>, <iono> clears
each assistance data type that is flagged as '1'.
Parameters:
<eph> (Ephemeris assistance data):

<alm> (Almanac assistance data):

Clear all GPS assistance data
This command clears GPS assistance details from the modem and puts
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:
•
AT!GPSCOLDSTART clears the modem's GPS details
