  5. 6. What is GPS? Developed by the U.S. Department of Defense for the military, the Global Positioning System (GPS) is a worldwide, satellite-based, radio navigation system that will give you the exact position of your vehicles, no matter where they are, what time it is, or what the weather is like. A total of 24 satellites orbit the Earth, monitored continuously by earth stations. The satellites transmit signals that can be detected by GPS receivers located in your vehicles and used to determine their location with great accuracy.
  6. 7. 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 atleast 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.
  7. 8. What is GSM ? GSM, Global system of Mobile, is a popular Mobile communication system provided by Cellular service providers or GSM Operators in most countries internationally. 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. GSM is required in Vehicle tracking systems because GPS system can normally only receive location information from satellites but cannot communicate back with them. Hence we need some other communication system like GSM to send this location information to central control room. Other technologies can also be used but they are more costly.
  8. 9. What is GPRS? General Packet Radio Service, is new communication services introduced by GSM operators. These services are part of same GSM network. These services allow secure and confirmed transfer of content like digital photos or other data to other GPRS capable system. example of services based on GPRS is MMS (Multimedia Messaging Service) GPRS is required in case we want to take snaps and transfer them to the central control room. They are not required for GPS tracking etc. GPRS does not involve additional hardware but we need to use more advanced GSM modules which support GPRS. GPRS services are not provided by all GSM operators.
  9. 10. 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.
  11. 12. 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&quot; software convert it into location and address on map for decision making.
