METHOD FOR LOCAL RADIO NAVIGATION BY SIGNALS OF UNSYNCHRONIZED DOMESTIC MEANS FOR ELECTRONIC SUPPRESSION OF GLOBAL NAVIGATION SATELLITE SYSTEMS Russian patent published in 2022 - IPC G01C21/00 

FIELD: radio navigation.

SUBSTANCE: invention relates to the field of radio navigation in the conditions of electronic warfare and can be used in the development of a local radio navigation system (LRN) based on the signals of unsynchronized domestic means of electronic suppression of global navigation satellite systems (GNSS). The purpose of the invention is to implement the function of alternative coordinate-time provision of authorized consumers (AC) by signals of unsynchronized domestic means of electronic suppression of GNSS. The expected result is provided by configuring the NASP in the following modes: “Preparation” (input of initial information into the NASP), “Synchronization” (reception of radio interference at the point of initial synchronization, calculation of corrections for out-of-sync and coordinates of the NASP, evaluation of the quality of initial synchronization), “Navigation” (reception of radio interference at an arbitrary point, measurement of delay values, calculation of current own coordinates of the NASP).

EFFECT: formation of an alternative coordinate-time support for the AC in the absence of synchronization of stations of intentional radio interference with each other and with the NASP.
