METHOD FOR LOCAL RADIO NAVIGATION OF A MOVING OBJECT Russian patent published in 2023 - IPC G01C21/00 G01C21/04 G01S5/02 G01S13/76 

FIELD: radio engineering.

SUBSTANCE: local radio navigation and radio communications aimed at obtaining estimates of the space-time state of a moving object. The claimed method of local radio navigation of a mobile object is based on the interaction of a mobile object equipped with a radio station, a monitoring control unit, a device for collecting data and calculating coordinates and a display, with RNS with known local coordinates, equipped with a transceiver. The method provides for the determination of own local coordinates of a moving object using the value of the time interval, proportional to the distance between the moving object and the RNS, measured by a moving object in a query way. Additionally, a direction finder is included in the RNS, which provides measurement of the bearing of a moving object relative to the RNS when receiving a range request signal from a moving object and transmitting the measured bearing value to the transceiver, which includes the bearing value in the range response signal for the mobile object. Determination of own local coordinates by a moving object is carried out by a goniometer-range method using additional information about the value of the bearing of the moving object, extracted from the range response signal received by the radio station of the moving object.

EFFECT: determining the coordinates of a moving object using a single reference navigation station (RNS) with known local coordinates by a query method by asynchronous radio exchange between the mobile object and the RNS.
