Positioning Methods

The main application of these systems – integrated provision of vehicles, provision of search for stolen vehicles. Methods for locating radio frequency. The location of the vehicle is determined by measuring the difference between the distances of the transport means of three or more relative positions. This group of methods can be divided into two groups: methods that implement the computation of coordinates on the results of the special reception of radio signals on board rolling stock object (the methods of direct or inverted radio navigation), and methods that are generally called for in this Article means Radiodirection an absolute or relative position of a moving object is determined by reception of radio signals emitted by a network of stationary or mobile receiving stations. Radio direction-finding methods using distributed through a network of finders, or using mobile direction-finding tools possible to track the location of objects, equipped with radio transmitters, beacons. Navigation methods are implemented on the basis of pulse-phase ground-based navigation systems (such as 'Loran-C "-' The Seagull") and medium-satellite navigation systems (SRNS) gps navstar – glonass. The best accuracy and performance now have satellite navigation systems, in which accuracy is achieved Positioning in the standard mode is not worse than 50-100 m, and the use of special methods for processing data signals in phase-detection mode or differential navigation – up to several meters. The advantage of data methods are a global positioning, it can be used on virtually any territories and lines of any length, good accuracy, the ability to determine an object's position on the map areas, the ability to determine not only the coordinates but also the height, speed and direction of motion of an object, a high degree of compatibility with automated information processing systems.
