About GPS Vehicle tracking system: Technologies involved in a Tracking system and How it works?
Modern technology is making fleet management more efficient and effective in addition to adding to vehicle safety and maintenance. Needless to say these systems are a considerable improvement in fleet management which has always been plagued by inaccessibility to driver and vehicle performance till after the fact.
Technologies Involved
• GPS – Global Positioning System
Allow GPS receiver to determine its exact POSITION in longitude and latitude, velocity, direction etc.
• GSM – Global System of Mobile
Allow this POSITION information to be sent to central control room as
SMS or GSM data call
• GPRS – General Packet Radio Service
Allow transfer of multimedia content like photograph to central control room or other mobile unit
• GIS – Geographical Information system
City maps with technical information which allow converting the POSITION information into possible address, street or place.
How does GPS work?
Each GPS satellite transmits radio signals that enable the GPS receivers to calculate where its (or your vehicles) location on the Earth and convert the calculations into geodetic latitude, longitude and velocity. A receiver needs signals from at least three GPS satellites to pinpoint your vehicle's position.
GPS Receivers commonly used in most Vehicle tracking systems can only receive data from GPS Satellites. They cannot communicate back with GPS or any other satellite.
A system based on GPS can only calculate its location but cannot send it to central control room. In order to do this they normally use GSM-GPRS Cellular networks connectivity using additional GSM modem/module.
IMPORTANT POINTS
- GPS Receiver can communicate (receive and send data) to GPS Satellites
WRONG, GPS Receiver can only receive data and cannot send data to Satellite (s)
• GPS Satellites know the position of your GPS receiver mounted on vehicle
WRONG, GPS satellites do not know the position of a GPS Receiver. GPS Receiver calculates its position using data from 3-4 satellites and no single satellite knows the calculations done by GPS receiver or its position.
- We need to pay GPS Satellite Company for enabling GPS receiver to receive data
WRONG, GPS Satellite service is freely available throughout the world; anyone anywhere can receive GPS data by buying any off-the-shelf GPS receivers.
• GPS Satellites are standard satellites like for Television broadcast, VSAT etc.
WRONG, GPS satellites are different satellites and can only send small and week radio signals to earth.
What is Automated Vehicle Location (AVL)?
AVL systems are computer-based vehicle tracking systems that use a positioning system-GPS (Global Positioning System), GSM (Global System of Mobile) and GIS (Geographical Information System). Vehicle locations are transmitted at regular intervals to dispatch center, where "GIS map matching" software convert it into location and address on map for decision making.
