What is GPS?<br />GPS (Global Positioning System) is a type of GNSS (Global Navigation Satellite Systems).<br />It allows small electronic receivers to determine the latitude, longitude and altitude of a point.<br />It uses time signals transmitted along a line of sight by radio from satellites.<br />Receivers calculate the precise time as well as position, which can be used as a reference for scientific experiments.<br />GPS uses 24 Medium Earth Orbit satellites (altitude of about 20,000 kms above the surface of the earth).<br />
How does GPS works?<br />GPS system consists of 3 pieces: space segment, the control segment, and the user segments.<br />The US Air Force maintains these segments.<br />Space segment are the satellites that transmit the position information.<br />Control segments are the ground stations that are used to control the satellites and update the information.<br />The user segments are the receiver that you purchased.<br />The receiver collects data from satellites and computes its location anywhere in the world based on the information it gets from satellites.<br />
"Provision of ACD Network" has been successfully commissioned recently on the Northeast Frontier Railway (of Indian Railways), covering 1736 Route km (of its Broad Gauge route).
Final commissioning trials of ACD network installed on 760 km of Konkan Railway route is presently underway.</li></li></ul><li>Future Scope<br />The cell phones are increasingly incorporating GPS technology.<br />GPS devices in cars will soon be a commonplace.<br />3-D modeling technology in GPS for anticipating vehicular traffic.<br />Controlling other devices using your cell phone.<br />
GSM (Global System for Mobile Communications)<br />Also known as the cellular phone network.<br />The geographical area is divided into hexagonal cells.<br />The device (cell phone) uses a SIM card. (Subscriber’s Identity Module).<br />It operates in 900/1800 MHz and 850/1950 MHz frequency range.<br />
