Abstract. In real conditions of application for high-precision positioning and trajectory control of unmanned aerial vehicles (UAVs) when flying along a route, insufficient noise immunity and operating accuracy of satellite navigation system receivers are manifested. In this regard, it is relevant to study possible methods and means of providing high-precision navigation definitions based on complex processing of signals from various sources of navigation information when solving the problem of displaying a UAV in a terminal set.

The article presents the results of developing a UAV trajectory control algorithm based on methods of statistical optimal control theory, the implementation of which will improve the accuracy of maintaining a given flight route. The characteristics for analyzing errors in maintaining the flight path are considered.

The results of modeling and research of the characteristics of the trajectory control algorithm for various configurations of navigation information sources (NIS) are presented and the dependence of the accuracy of maintaining a given UAV flight route on errors in estimating navigation parameters is shown.

Keywords: trajectory control, unmanned aerial vehicle, Letov-Kalman algorithm, sources of navigation information, automatic dependent surveillance.
