NAVIGATION METHOD USING USER TERMINAL AND USER TERMINAL Russian patent published in 2025 - IPC G01S1/24 G01C21/00 

FIELD: radio navigation.

SUBSTANCE: invention relates to radio navigation, enables to implement noise immunity of a radio navigation system and to provide high-precision positioning of moving objects. Disclosed is a navigation method using a subscriber terminal and a subscriber terminal, which provide high-precision positioning using a navigation signal which is free from the effect of the ionosphere and errors in determining satellite ephemerides, independent of global navigation satellite systems, solving both the positioning task and the object monitoring task, using request and requestless modes, ranging and differential-ranging methods of positioning, characterized by using a noise-immune method of correlation processing of a signal code, as well as resistance to generated simulation interference using dynamically varying according to a complex law pseudorandom sequences (PRS), resistance to retransmitted simulation interference using methods of combating re-reflected signals, resistance to masking interference using high-power noise-like signals at the receiving point.

EFFECT: providing high-precision positioning in the absence of signals of global navigation satellite systems using a basic user terminal, operating in interrogation and non-interrogation modes using ranging and differential-ranging methods of positioning and an original method of correlation processing of noise-like signals, which provides centimetre accuracy of positioning and high resistance to masking and simulation interference.
