Principle and application of GPS

GPS principle is simply to determine the target coordinates through the navigation satellite, and then map coordinates to determine the specific location of the target. GPS positioning principle is based on the high speed motion of the satellite instantaneous position as the known starting data, the use of spatial distance resection method to determine the location of the point to be measured. The global positioning system is a radio space positioning system, it uses the navigation satellite and the ground station to provide all-weather and global high precision, continuous and real-time three-dimensional coordinates (latitude, longitude, elevation), three-dimensional velocity and location information anywhere on the earth's surface for positioning and navigation.

Mobile GPS positioning charges it?

GPS is free of chargeThe following is a brief introduction to GPS:GPS is the English Global Positioning System (global positioning system). GPS began in 1958, a U.S. military project, put into use in 1964. 1970s, the United States Army and Navy jointly developed a new generation of satellite positioning system GPS. The main purpose is for the sea and air three major areas to provide real-time, all-weather and global navigation service, and for information gathering, nuclear monitoring and emergency communication etc. some military purposes, through the experimental study of more than 20 years, at a cost of $30 billion, by 1994, global coverage of 24 GPS satellites constellation has set up to 98% completeNow there is an auxiliary GPS positioning service called A-GPS this is based on the operator's base station location, may charge a certain amount of traffic charges. (for example: some authority shoes should have seen, some rights management will prompt the XXX program through cell base station (or write "GPS") to obtain location information, whether you allow such hints, here is the A-GPS cell base station technology, GPS GPS technology is a natural ~)But GPS is the United States, the use of positioning satellites are U.S. satellites, that is, if you use GPS, then you will be all the way in the United States under the nose,So China also launched the Beidou satellite navigation system a long time ago, but even now, the system has not been known to the public

Bad weather will affect the GPS locator accept signal

Will affect the GPS is based on the above satellite transmission of information, if blocked, the message will be transmitted a little error
