How does the SafeTrac Tracer 100 GPS Vehicle Tracking System work?
The SafeTrac Tracer 100 provides three main functions:
-
Providing position
information (via the on-board GPS)
-
Storing that position
information until it is needed (stored in the on-board memory)
-
Transmitting that
position from vehicle to base-station (via the unique STACC
communication protocols)
Positional information for
each vehicle is provided through the use of Global Positioning System
receiver which resides within the SafeTrac Tracer 100 on each vehicle.
The Global Positioning System (GPS) is a world-wide radio-navigation
system formed from a constellation of 24 satellites and their ground
stations, developed and controlled by the US Department of Defence.
These satellites transmit constant orbital position information, very
precise time information, and any error corrections that need to be
taken in consideration when making calculations based on this
information. The GPS vehicle tracking system receiver in the SafeTrac Tracer 100 interprets the
signals broadcast by at least three satellites to "triangulate" a
general position. Triangulation requires the receiver to use the clock
reading, location, and orbit of each satellite and mathematically
determine its relative location. A fourth satellite is used for time
corrections between the GPS receiver and satellite's clocks.
Storing
Location
With the
benefit of the on-board memory within the SafeTrac
Tracer 100, positional information can be stored ready
for transmission to the base station. The frequency with which you
communicate with your assets is very much your choice.
You may
wish to track you vehicle every 2 minutes, or you may only want to know
their positions twice a day. Whichever you choose, you can be sure that
the on-board memory will pass all the positional information to you for
the entire period. The SafeTrac Tracer 100 stores it all until you need it. We have clients whose vehicles are on
the continent for an entire week - the routes they take are then
downloaded when they return and analysed. This costs them a single
2-minute call to the vehicle. Imagine - 2 weeks of tracks for the cost
of 1 phone call! Nice I am sure you will agree, Use the form for further information about the Tracer 100 GPS Vehicle Tracking System.
