LT6 GPS/AVL Cellular Modem

The Industry Standard for GPS/AVL Fleet and Asset Management Systems

Intelligence. Versatility. Control.

The LT6 GPS/AVL GPRS Cellular Modem is the backbone of the Navigo GPS/AVL Fleet Management System. Location Technologies offers complete GPS/AVL Fleet and Asset Management Systems by combining our LT6 GPS/AVL Modem series and our Navigo Mapping Software solutions. Available in both desktop and web based version the Navigo suite of Fleet Management and Mapping Software fits into any application and budget.

Affordable GPS Based AVL

With a per-vehicle cost that is less than what you would pay for most two-way radios, the LT6 is a cost effective tool for all fleet operations, large and small.

Dynamic Intelligence

In addition to a high-sensitivity SIRFIII GPS receiver the LT6 GPS/AVL GPRS Modem ships standard with a wide variety of inputs and outputs including 2 external com ports, 8 digital inputs, 6 Analog Inputs, and 4 Analog Outputs for remote control.

Essential Versatility

Our years of industry specific engineering experience gives you the ability to monitor virtually any fleet operations using some combination of the available analog/digital inputs. We have developed interface configurations for industry standard applications such as Snow Plows, Solid Waste, Sweepers, Public Safety, Transit, and many more.

Unrivaled Control

The LT6 GPS/AVL GPRS Cellular Modem is capable of monitoring and reporting a variety of analog and digital inputs. There are also up to four analog outputs available for remote control. This generic I/O capability is fully software configurable. Examples might include door lock control, ignition circuit defeat, light and emergency switch monitor, temperature, shock, and humidity. Standard interface packages are available for street maintenance vehicles such as plows, spreader, vacuum, and sweeper vehicles.

Digital Inputs

Each AVL device may monitor up to 8 generic digital inputs. The 8 inputs may be used to trigger various events on the map. For instance a digital input may be tied to a hydraulic pressure switch that indicates the up or down position of a snow remove blade. When the blade is down the system could be set to plot a blue path behind the vehicle. This would indicate that the path had been plowed. Digital inputs may be programmed to plot paths, display messages, mark spots on the map, or change the vehicles color.

Analog Inputs

Six inputs may be used to monitor analog levels in the vehicle. An example would be battery voltage. Similar map actions as described for digital inputs are available when a given inputdrops below or rises above preset levels.

Location Technologies’ 6th Generation of Engineering Excellence

All LTI GPS Modules use a state of the art high-sensitivity SIRFIII GPS receiver to ensure fast time-to-first-fix times and continuous tracking in the most challenging environments.

The LT6 GPS/AVL GPRS Modem also hosts two RS-232 ports for connection to external peripherals such as laptop computers, text messaging terminals, and simple push button status heads. LTI offers laptop software for mobile data messaging, mobile mapping, remote database operation, LT MDT Mobile Data Terminal, and the LT MDC.

Mobile Data Terminal and Personal Navigation Device Integration

LTI offers a variety of mobile data options. These include our own LTMDC Mobile Data Computer, LTMDT Mobile Data Terminal, Laptop interfaces, and our Garmin Navigation Device interface.
