GPS

Table D-9: GPS AT Commands

Command Description

*GPSDATA? Query the device and provides a snap-shot of GPS data.

This command is independent of all GPS configuration. You don't need to have a server

configured or any specific report type selected. The response to this command lists the fix

status, satellite count, and latitude and longitude in decimal degrees. It is not formatted as a

GPS report. For example:

AT*GPSDATA? returns:

GPS Fix=1

Satellite Count=8

Latitude=+49.17081

Longitude=-123.06970

*PGPS Query or set the serial streaming interface ports that the reports are sent to.

AT*PGPS? to query

AT*PGPS=n to set

•n=0—None

• n=1—DB9 Serial

• n=2—USB Serial

• n=3—DB9 and USB

• n=4—I/O X-Card Serial

• n=5—I/O X-Card Serial and DB9

• n=6— I/O X-Card Serial and USB

• n=7—I/O X-Card Serial, DB9 and USB

*PGPSC Query or set the out-of-coverage setting. This setting enables you to configure the AirLink

device to stream GPS reports to the serial port only when the device has no cellular

coverage. (This enables you to use a back-up in-vehicle mapping application that does not

rely on cellular network coverage.

AT*PGPSC? to query

AT*PGPSC=n to set

• n=0: ALWAYS (default) GPS reports are always streamed to the serial port

• n=1: Out of Coverage—GPS reports are only streamed to the serial port when the

AirLink device has no cellular network connection.

Note: The two persistent GPS report parameters, *PGPSR and *PGPSF, control the report

type and message frequency of reports sent out the serial port when the AirLink device is

out of cellular network coverage.
