What is gps in the mobile device and what to pay for it, buying a mobile? Often come across people who think that is quite knowledgeable on this issue. In reality, the picture is somewhat different. I will try very briefly and accurately describe the essence, the most needed nuggets of knowledge in this area. (News for cis citizens with nokia phones with integrated GPS-module, or who intend to buy it) Question 1. Communication gps and mobile operator. Justin Kan has much to offer in this field.

Short of the gps. For more information see this site: Kenneth Feinberg. gps – satellite system, developed by the Department of Defense to determine the exact coordinates and motion parameters of objects for further processing and use in navigation systems and guidance systems precision weapons. The structure consists of gps satellites and ground stations to service, combined into a single network, as well as consumers (subscribers) using GPS-receivers, which process from the satellite signals and calculate them on your location and parameters. Conclusion: To use the GPS-receiver on your mobile device with any service operators of cellular communication unnecessary. You can even sim card into the phone do not embed. The system worked even before the mass use of cellular networks and continues to work now in any country at any point on Earth's surface and around it. All that is needed – the presence of GPS-receiver, the presence of appropriate program of interaction with him and navigational charts. In today's cell phones use a combined system of coordinates A-GPS, which processes the data, such as by satellite, and with basic stations of the cellular operator, but in the cis mobile operators still do not give the source data for processing – that's why gps works fine without them.
