AT+CTKG GPS Configure
The AT+CTKG command configures the GPS parameters. This command
mirrors the functionality of the over-the-air GPS_CONFIG message. It can query
the current settings or change them to new values. Unless you are very familiar
with the types of parameters listed below and how changes will effect overall
GPS performance in any given application environment, it is recommended that
you leave these parameters at their factory default settings.
