Examples:
Setting the rate for geospatial information messages to 1 per second:
$GS 1*05
$GS OK*30
If <rate> is valid, no $GN messages will be sent by the device until the GPS has obtained a
valid position reference as indicated by the $M138 POSITION*2d message .
Calling the most recent geospatial information message:
$GS @*74
$GS 109,214,9,0,G3*46
Returns an HDOP of 1.09, VDOP of 2.14, the device is using 9 GNSS satellites for this solution,
and it is a Standalone 3D solution.
Querying the rate of geospatial information messages:
$GS ?*0b
$GS 120*07
Returns a rate of one message every 120 seconds.
