Step Global SGDR-001 dead reckoning module for the Trimble TM3000

Wednesday, 20 October, 2010 | Supplied by: Step Global Pty Ltd


The SGDR-001 dead reckoning solution for the Trimble TM3000 can also be used as a stand-alone solution. It uses the Trimble Lassen iQ+DR module as its engine.

Dead reckoning is suitable for vehicles that travel through areas where GPS signals are not able to penetrate. These areas include tunnels, underground and multistorey car parks and canyons with limited open sky.

The SGDR-001 module uses an onboard gyro with speed and direction inputs from the vehicle to determine its position when GPS signals are lost.

The module has been designed to provide a rugged DR solution for a range of vehicles from trains, buses and heavy haulage to emergency services.

Key features of the device are: signal conditioned vehicle speed and direction inputs; motor vehicle-grade voltage regulator, 9-32 V input with reverse polarity detection; RS232 serial interface; reset input; onboard gyro; available in a rugged aluminium enclosure or PCB module form.

A specific SGDR-001 interface for the Trimble TM3000 has also been developed. The TM3000 manages the SGDR-001 and takes the DR readings when it loses normal GPS signals.

Trimble’s TM3000 asset tracking device is an open and flexible platform that can be adapted to a broad range of vehicle/asset monitoring, management and recovery services.

The device integrates a GSM/GPRS modem, a GPS receiver, three-axis accelerometer, digital and analog inputs and outputs, two RS232 ports, battery backup, rugged motor vehicle-grade power regulator, extensive data log, over-the-air configuration, an independent application subsystem and an array of peripheral interfaces in a small, robust package.

Functions that can be achieved with the TM3000 deployed in assets/vehicles include: locate the position of assets/vehicles at all times; monitor vehicle conditions; warn operators on safety conditions; remotely operate systems on board the vehicle; communicate from monitoring centre to vehicle operator; measure fuel consumption; measure engine idle times; monitor vehicle operator’s driving behaviour for excessive braking, swerving and acceleration; remotely monitor operation of peripheral equipment attached to vehicle; accurate capture of FBT information; security alerts on out-of-hours operation; alert on un-authorised use of vehicles; accurately measure driver hours and alert on excessive hours.
