Mobile GPS positioning charges it?

Answer:

This is no charge, GPRS is a satellite positioning system. But with the phone, it will produce a certain amount of traffic, but not much.
GPS positioning: free. As long as your phone has a way to receive the GPS satellite signal. GPS has a high accuracy, which is generally used for military, or national, and for special purposes. And we usually use the lower accuracy. For azimuth positioning. Low positioning accuracy.
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
Do not charge, even if there is no SIM card can also be used, you can do an experiment.
