1. Introduction

1.1 Introduction

GTR-128/GTR-129 is designed as durable and multi-functional GPS/GSM/GPRS tracker. It
integrates highly sensitive GPS module and quad-band GSM communication module with a
powerful microcontroller that fits into a compact enclosure. The device is capable of waterproof
and ideal for use in motorcycle, golf cars and general car. It is small size and low cost for covert
and efficient tracking device. It provides real-time GPS positions anytime and anywhere with an
open view to the sky, and offers precise positioning, and reports vehicle status to the server with
necessary information shown on the map. Benefits such as enhanced fleet management,
improved vehicle safety, emergency response, are all accomplished through the implementation
of the GTR-128/GTR-129 system. The built-in GSM and GPS antennas are for easy installation
without hassle.
