Problem statement. One of the main information systems of complexes with unmanned aerial vehicles is the coordinate-time navigation support system. The key element of this system is the navigation equipment of the global navigation satellite system consumers. The navigation equipment of unmanned aerial vehicle consumers is exposed to destabilizing factors during operation. Among them, a special danger is presented by deliberate imitation interference, the effect of which on the navigation equipment of consumers leads to a latent failure that is not detected by standard means of technical diagnostics. Therefore, the task of increasing the reliability of technical diagnostics of the navigation equipment of consumers under the influence of deliberate imitation interference is urgent. Purpose. Development of a methodology for technical diagnostics of consumer navigation equipment as an integral part of the coordinate-time navigation support system for an unmanned aerial vehicle under conditions of deliberate imitation interference.

Results. A technique has been developed for technical diagnostics of navigation equipment of unmanned aerial vehicle consumers, based on the complex processing of information coming from the navigation equipment of consumers and external sources of information. The proposed technique provides the specified reliability of technical diagnostics, determined by the conditional probability of undetected failure no more than 10-7 in a time significantly less than the time interval determined by the requirements for the integrity of the GNSS. Practical significance. The developed technique can be used to improve the mathematical support of the built-in automatic system for technical diagnostics of the coordinate-time navigation system for complexes with unmanned aerial vehicles. This will make it possible in practice to increase the reliability of technical diagnostics of navigation equipment for consumers of the global navigation satellite system under conditions of deliberate imitation interference.
