Problem formulation. Combat experience in local wars and armed conflicts has demonstrated the high effectiveness of military unmanned aerial vehicles (UAVs) in overcoming air defense zones. Analysis of modern air defense detection systems reveals that mini and small UAVs, characterized by low radar cross-section and capable of flying at ultra-low altitudes (up to 30 m) at speeds up to
100 km/h, successfully penetrate air defense zones. A critical requirement for UAVs is ensuring the required navigation accuracy for reaching a designated area under conditions of enemy electronic warfare (EW) countermeasures. An analysis of existing navigation systems shows that those used in military mini and small UAVs fail to meet accuracy, jamming resistance, and size-weight requirements, preventing autonomous UAV operation in modern combat scenarios.

Purpose. To achieve the required accuracy of a UAV navigation system that ensures operation under EW countermeasures and ultra-low-altitude flight conditions through the development of a Video-Inertial Navigation System (VINS).

Results. An algorithm for real-time coordinate reckoning in VINS has been developed, distinguished by the use of a monocular video stream of the Earth’s surface and signals from a three-component gyroscope. The algorithm is based on a coordinate reckoning method that calculates UAV coordinates while compensating for gyro block drift.

Practical significance. The study provides recommendations for improving the algorithmic support of UAV navigation systems, ensuring the required accuracy of coordinate determination, enhancing autonomy, jamming resistance, and safety during combat missions to destroy ground targets under conditions of suppressed navigation and control channels.
