1 Introduction
1.1 About the GSM/GPRS MT-GL
The GSM/GPRS MT-GL (hereafter referred to as “MT-GL”) is an Automated Vehicle Locating (AVL)
device that utilizes a GSM/GPRS modem and a Global Positioning Satellite (GPS) module. Working
together, these technologies allow the MT-GL to simultaneously act as a stand alone GPS reporting
device and wireless data retrieval unit. The MT-GL provides a flexible AVL solution with Input/Output
(I/O), six selectable National Maritime Electronics Association (NMEA) GPS data format, Trimble
ASCII Interface Protocol (TAIP) GPS data format, and Enfora’s own proprietary Binary GPS data
format. The MT-GL is designed to work in a stand-alone device in an automobile. Enfora’s MT-GL
provides maximum AVL versatility in a single affordable device.
