Problem statement. In conditions of interference to global navigation satellite systems (GNSS), coordinate and time support for consumers (e.g. aircraft) can be implemented within the framework of a local navigation system (LNS). In [4] a method of local radio navigation based on signals from non-synchronized domestic GNSS electronic countermeasures is proposed. The disadvantage of this method is the need to implement an additional “Synchronization” mode, during which time corrections are calculated that take into account the desynchronization in the operation of radio interference transmitters and the consumer navigation equipment (CNE) of the LNS.

Purpose. Development of a method for determining aircraft coordinates using interference signals from unsynchronized GNSS radio interference transmitters without implementing an additional initial synchronization mode for the CNE.

Results. A method has been developed for determining the coordinates of an aircraft using signals from unsynchronized GNSS jammers, ensuring the determination of the coordinates of an aircraft without implementing an additional initial synchronization mode for the CNE. The developed method ensures aircraft positioning accuracy of 300 m at a distance of 55 km from the transmitters with a transmitter base width of 30 km and a bearing error of no more than 0.5°.

Practical significance. The presented results can be used in the field of radio navigation in the development of LNS, built into the spatially distributed interference system of the CNE GNSS.
