The paper considers the possibility of solving the problem of determining the location of an unmanned aerial vehicle (UAV) using specialized computing device. The mission statement addresses the determination of the coordinates of UAV based on the coordinates located at a relatively short distance from the start of the local coordinate system of groups of fours beacons and range from the UAV to the beacons. Based on the available data for each group is formed in the standard navigation system rangefinder four equations, which is converted to the third-order linear systems. The solution of this linear systems with continuous variables constant terms determines the coordinates of the UAV. The paper discusses the features of algorithmization solve the problem of determining the location of the UAV ground when preparing the proposed tasks and solving problems on board UAVs in real time. The investigation of the possibility of using second-order delta-transformations for solving linear systems in the task at different examples of beacons placement. The results of experiments using computer simulations confirm the possibility of solving the linear in one iteration in a steady course with a time step of practical concern, and the beginning set the process is provided at a sufficiently large distance from the origin. . Keywords: Aircraft position finding, linear system solution, second order delta-transformation, aircraft special-purpose calculating unit.
