METHOD OF LOCATING USER TERMINALS MOVING IN COVERAGE AREA OF LOCAL NAVIGATION SYSTEM Russian patent published in 2024 - IPC G01S5/14 G01S3/46 G01S7/00 G01C21/00 

FIELD: navigation equipment.

SUBSTANCE: invention relates to navigation equipment and can be used for high-precision determination of coordinates of a consumer in interference conditions, including mobile objects moving in the coverage area of a local navigation system (LNS). Disclosed method realizes formation of a navigation field of high accuracy, which is resistant to interference. Local navigation system navigation field is created by radio navigation reference stations synchronously transmitting radio navigation signals, which use dynamically changing according to a complex law pseudorandom sequences containing information on their location, time and weather conditions, which are received by a subscriber terminal, which determines its location by a non-interrogation method, wherein the control-correcting station determines the range to the radio navigation reference stations by the interrogation method, which is then compared with the pseudo ranges to the radio navigation reference stations obtained by the non-interrogation method, for estimation of mutual desynchronization of radio navigation reference stations clocks.

EFFECT: high accuracy and resistance to interference of a navigation field generated by a local navigation system.
