Problem statement. Currently, the navigation equipment of consumers of global navigation satellite systems (GPS GNSS) uses a method of blocking a false signal (simulating interference) by disabling the processing channel in which the presence of a questionable signal is recorded, which eliminates the use of false estimates of radio navigation parameters and navigation messages when solving the problem of navigation definitions. The method used to block false navigation signals requires an excessive number of processing channels, while an excessively multi-channel GNSS system has a high cost, significant weight and power consumption, making it difficult to use it as part of mobile mobile objects, for example, on small, small-sized unmanned aerial vehicles.

Purpose. Development of a technical solution that will block the negative effects of false navigation signals (simulating interference) the accuracy of solving the problem of navigation definitions when using a minimum number of channels for processing navigation signals in the GNSS system.

Results. The proposed technical solution will allow for increased efficiency.

Practical significance. The presented results can be used in the field of radio navigation in the development of an interference-resistant low-channel GNSS system.
