Open CTM (Revision D)

Connecting to a CTM-15X Modem Locally

For a “cold” start (after all power is applied to the modem) the acquisition time typically will be less than

50 seconds.

For a “warm” start (standby power is maintained to the CTM-15x) the acquisition time will typically be

less than 38 seconds.

For reacquisition (after the GPS module has temporarily lost signal) the time to acquire a valid position fix

is typically less than 2 seconds.

The GPS information can be sent by the device as a message in any of the configured reports.

The GPS receiver uses the WGS-84 datum.

The CTM-15X (running firmware version R1.3.0 or above only) supports GPS data from a external GPS

device connected to the modem via USB or serial port, or from a wireless module via A-GPS (Sierra

Wireless devices only). When the CTM-15x has been configured to use an external GPS or an A-GPS

device, the GPS LED will reflect the current status of the selected GPS device.
