Command Reference

If all enabled ports are available and have valid GPS, the highest priority input is used.

Notes:

This can feature can also be used for A-GPS since it is outputting NMEA data on a ttyUSB port.

When GPS inputs are configured at the same priority, GPS data will be obtained from whichever

GPS input has valid data first, in ascending order from GPS input 0 to GPS input 3.

Example:

cmd gpsparam 3 2 /dev/ttyUSB0 4800 8 n 1 0 configure the modem USB port for

accepting GPS data

cmd gpsparam 3 2 /dev/ttyS0 4800 8 n 1 0 configure the modem external serial

port for accepting GPS data

A cmd save and a powercycle is required for this command to take effect.

gpspos n ±xx.xxxxxx ±yyy.yyyyyy

Set fixed GPS position mode. This sets the GPS coordinates used in modem reports to user-defined

latitude and longitude values. When this setting is enabled, the GPS date and time used in modem

reports is synchronized to the modem's system time.

This setting is used for monitoring modems used with fixed-site applications.

n = 0 Disable fixed GPS position mode. Use GPS position from GPS input device configured with gpsinput.

(Default)

n = 1 Enable fixed GPS position mode. Use user-defined location.

±xx.xxxxxx = -90.000000 <= ±xx.xxxxxx <= +90.000000 latitude in decimal format, where North=positive

and South=negative

±yyy.yyyyyy = -180.000000 <= ±yyy.yyyyyy <= +180.000000 longitude in decimal format where

East=positive and West=negative

A cmd save and a power cycle are required for this command to take effect.

Notes:

cmd gpspos 0 will disable the fixed GPS position mode but preserve the user-defined location

cmd gpspos 0 0 0 will disable the fixed GPS position mode and clear the user-defined location
