What is a GPS positioning system?
- GPS system compositionGPS system has three major components, namely, the space constellation, ground monitoring and user equipment. Space constellation in GPS 24 satellites distributed evenly in 6 orbital planes, orbital plane angle relative to the equatorial plane is 55 degrees, the angle between the plane of the orbit is 60 degrees, each satellite orbital plane 90 degrees, either on the satellite orbit plane than in the west adjacent corresponding satellite orbital plane the lead on 30 degrees. The average altitude of the satellite orbit is 20200km, and the satellite running period is 11 hours and 58 minutes. Each satellite every day about 5 hours above the horizon, and at the same time the number of satellites above the horizon varies with time and location are different, can be 4~11; the ground monitoring part of GPS at present mainly by the distribution in 5 ground stations around the world, including the injection station inspection station, master station and information. The space part and ground monitoring part of the GPS is the basis of the navigation and positioning of the system which is widely used by the user, which is controlled by the United States. The user equipment of the GPS is mainly composed of the receiver hardware and processing software. The user receives the GPS satellite signal through the user equipment, obtains the user position, the speed and so on through the signal processing, finally realizes uses GPS to carry on the navigation and the localization goal.s
