FIELD: radar ranging and radio navigation.
SUBSTANCE: invention relates to radio navigation and can be used in local radio navigation systems in rugged terrain, the lack of signals of a global satellite navigation system in a complex signal-interfering environment. Technical result is achieved by the fact that in order to achieve the electromagnetic availability of user signals, radio navigation support points (RNSP) are raised above the Earth's surface using quadrocopters (hectcopters). All signal processing is performed at a central processing point. To improve the signal-to-noise ratio when the phase difference of the relayed signals is changed, the noise subtraction algorithm is used. Additionally, there are suggestions for optimizing the structure of the local radio navigation system by the number of RNSPs and their placement on the ground.
EFFECT: ensuring the operability of the local navigation system in the most difficult conditions of its operation.
