9 GPS Operation and Verification
The Mini-MT contains an integrated GPS receiver and GPS antenna. For best GPS
performance the unit should be placed in an area where it can have direct view of the sky.
9.1 Verification of GPS Lock
The Mini-MT will provide an indication of successful GPS Lock within approximately
70 seconds when in view of satellites.
The GPS LED will flash yellow when it is receiving a sufficient number of satellites to
provide status. When this occurs, the internal GPS receiver has enough information to
track its current position.
9.2 Verify GPS operation
The Mini-MT GPS status may be obtained locally through the USB connection or
through the GPRS connection to a server. The following steps allow the user to
determine GPS operation through a terminal program and also through the Enfora
Demonstration web server.
