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.
