The
GPS-130 is a commercial, low cost version of the GPS-150 Automatic Vehicle Location module compatible with
the Global Positioning System (GPS) that comes complete with an integrated wireless data
modem to communicate through any popular conventional or trunking 2-way
radio infrastructure.

Using pioneering techniques, the GPS-150 utilizes the most sophisticated form of Automatic
Vehicle Location (AVL). This is called the Global Positioning System and is a
constellation of 24 satellites developed by the U.S. Department of Defense, and made
available without charge to commercial and civilian users.
The unit will operate over any voice grade channel or
dedicated data network and is compatible with virtually any radio
transmission device.
