LT6 GPS/AVL Radio Modem

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

Intelligence. Versatility. Control.

The LT6 GPS/AVL Radio 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.

Location Technologies’ 6th Generation of Engineering Excellence

The LT6 GPS/AVL Radio Modem is literally our 6th generation of GPS/AVL modems. Our generic radio interface has been developed through years of experience in the two-way field.

We have interfaced into virtually every type of two-way radio and network type. The LT6 GPS/AVL Radio Modem integrates with all major trunking types and can channel steer most modern radios.

More than a Radio Modem

In addition to an onboard generic interface Radio Modem and High-Sensitivity SIRFIII GPS receiver the LT6 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. All key modem parameters are firmware based, flash programmable, and many can be set over the air.

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.

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.

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.
