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.
