Initiate a GPS position fix
This command initiates a GPS position fix.
Usage:
• AT!GPSFIX=<fixType>, <maxTime>, <maxDist> initiates a time-limited
position fix with a specified accuracy.
• AT!GPSFIX=? returns supported <fixType>, <maxTime>, and
<maxDist> values.
Parameters:
<fixType> (Type of fix to establish)
• 1—Standalone (not supported by a mobile station)
• 2—MS-based only
• 3—MS-assisted only
<maxTime> (Maximum time to wait for a position fix)
• 0–255 — Number of seconds to wait
<maxDist> (Requested accuracy of fix)
• Entered in decimal format
• 0–0xFFFFFFEF—Accuracy (in meters) requested for the fix
• 0xFFFFFFF0—No preference
Example:
AT!GPSFIX=1, 15, 10 requests a standalone position fix to 10 meters
accuracy. The request will fail (timeout) if the modem cannot determine a
position fix within 15 seconds.
One of the following responses will be received:
• “OK” if the request is successful, or
• “ERROR CODE = <value>” if the request fails for any reason. See
Table 8-3 on page 139 for a list of error codes.
Example:
• AT!GPSSTATUS (page 129)—Use this command while the tracking
session is in progress.
• AT!GPSLOC (page 123)—Use this command after the session
completes to obtain the result.
