Introduction

For radio systems range navigation and landing systems are providing positioning of the aircraft (aircraft) at a distance of 500 km with respect to the beacon, and the position of the aircraft relative to the runway while landing. Depending on the type of aircraft on board can be installed navigation and landing equipment or complex system of short-range navigation and landing.

The basis of short-range navigation systems (PRS) - a network of independent ground beacons (RM), which defines the parameters of the navigation. There are azimuth, long-range and long-range azimuthal beacons (RM), which is mounted on the ground and in the points corresponding to the characteristic parts of the airways. For RLS allocated plots the range of meter and decimeter waves, so their range of action is limited to a range of line of sight.

Navigation options range navigation systems - bearing and distance are determined on the aircraft with respect to the radio navigation points

Types range navigation systems differ since the informative signal parameter used to determine navigation parameters, as well as the structure of the system as a whole. The most widely used system RSBN domestic and foreign ICAO standardized system VOR / DME.
