Research Agency (DARPA) began development of a new global positioning system, which will replace the traditional GPS. Location tracking technology will be more stable, reliable and energy efficient.
Currently, a satellite navigation system has certain drawbacks, for example, the ability to suppress signal GPS, as well as the existence of "dead zones" where there is no reception of satellite data. And if it is for ordinary users, most often, is not critical, during the conduct of hostilities could lead to unpredictable consequences.
The new technology created by the Defense Advanced Research Agency under the Ministry of Defense, to avoid the problems associated with radio interference and "dead" zones. High precision navigation of a new generation developed as part of Adaptable Navigation Systems (ANS) and will use multiple systems determine the position.
First, the self-calibrating gauges are applied, which will track the movements made after the last connection to the satellites. For example, after the last connection to the GPS vehicle moved to 3 km in area where there is no signal, but a stand-alone system for determining the movement pinpoints the location, starting from the most recently registered point.
Another promising development is the system of ASPN, which allows you to determine the location from all the available radio - cellular network television signals, radio and even lightning. Such developments may be useful not only during the war, but also to improve consumer electronics.
Autonomous positioning system will allow smartphones are much less likely to connect to satellites, which will save a lot of energy. To date, satellite navigation is one of the most energy-intensive modes of operation for mobile devices.
Setting the ANS will be made on a variety of devices, from smartphones and tablets to tanks and ships.
