At the present stage of its development, Global Satellite Navigation Systems (GNSS) have insufficient integrity, noise immunity, and in some cases, the accuracy of the navigation field, which reduces the effectiveness of their use for solving aircraft landing problems. Improve the accuracy of the integrated GNSS navigation field by using mobile pseudosatellites mounted on unmanned aerial vehicles (UAVs). To achieve the highest accuracy of the created integrated navigation field GNSS, a new approach is proposed based on optimizing the flight paths of the UAV. The problem of finding optimal UAV trajectories with pseudosatellites placed on them is solved using the Hooke-Jeeves method. As an optimization criterion, the minimum geometric factor (GF) is proposed at the points of the flexible landing trajectory of the aircraft. The features of the formation of optimal UAV trajectories for various applications, as well as when using various components of the GF as optimization criteria, are studied. Practical recommendations are given for choosing the optimization criterion and restrictions on the conditions for using UAVs with pseudosatellites placed on them are determined.
