How our system works
Introduction to GPS Vehicle Tracking Technology
• GPS – Global Positioning System
Allow GPS receiver to determine its exact POSITION in longitude and latitude, velocity, direction etc.
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, Voice
• GPRS – General Packet Radio Service
Allow transfer of multimedia content (data, photograph, ...) to central control room or other mobile unit
• GIS – Geographical Information System
Information System composed of Database, Software, Cartographic Data and programmable treatments which allow converting the POSITION information into possible address, street or place.

Developed by the U.S. Department of Defense for the military, and declassified under the Clinton Administration, the Global Positioning System (GPS) is a worldwide, satellite-based, radio navigation system that give you the exact position (5 to 10 meters) of your mobiles, no matter where they are, what time it is, or what the weather is like. A total of 24 satellites orbit around the Earth, monitored continuously by earth stations transmit signals that can be detected by GPS receivers located in your vehicles or in your hand for personal tracking. These signals are then used to determine the mobile's location with great accuracy.
How does GPS work?
Each GPS satellite transmits radio signals that enable the GPS receivers to calculate their (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. In order to perform this task, they normally use GSM-GPRS Cellular networks connectivity using additional GSM modem/module.GSM, Global System of Mobile, is a popular mobile communication system provided by Cellular Service providers or GSM Operators in most countries. It is used for in most mobile handsets used by us. GSM Mobile communication system can be intelligently used by electronic devices which can collect some data and send it to the central place using SMS or GSM data call.
What is GIS?
Geographical Information System, GIS is a software which consist of specially developed comprehensive and detailed maps of the city with longitude and latitude information of each place, street, junctions and address. These maps are useful to locate the address of a vehicle fitted with GPS system.GPS-GSM system only provide the longitude and latitude of the vehicle but GIS software if properly developed can provide details of exact or nearby address where the vehicle is.
In case one does not have detailed GIS maps of the city it would be very difficult to track and teach the vehicle in very short time.
