Problem statement. The functioning of the navigation equipment of consumers of global navigation satellite systems is carried out against the background of the impact of a set of intentional interference. One of the types of intentional interference is simulated interference, which leads to the issuance of false information about the location, speed and current time by the navigation equipment of consumers. However, the issues of assessing the effectiveness of the navigation equipment of consumers of global navigation satellite systems under the influence of simulated interference have not been fully investigated.

Purpose. Determination of the characteristics of detection of navigation signals and simulating interference of the search and detection system of navigation equipment of consumers of global navigation satellite systems.

Results. The mathematical modeling method has been used to obtain the characteristics of detecting navigation signals and simulating interference for three search cycles from the interference/signal ratio for different values of the probability of false alarms.

Practical significance. The results can be used by specialists in the field of satellite radio navigation in the development of software and hardware to protect domestic navigation equipment of consumers of global navigation satellite systems from simulated interference.
