Abstract. Rapid development of unmanned aircraft systems (UAS) and their application areas requires safe and efficient airspace (AS) for various categories of its users. One of the important tasks when using AS is planning a trajectory and flying the unmanned aerial vehicles (UAV) with account of the accuracy characteristics of on-board navigation systems. The paper presents a methodology for experimentally evaluating the accuracy characteristics of the on-board navigation system of the DJI MAVIC 2 ZOOM quadcopter. The methodology is based on the formation of a UAV desired track, with the help of which it is possible to estimate the deviation error in one of the horizontal coordinates and altitude. The experiments were conducted for real UAV flights at different altitudes and speeds. Semi-natural experiments were conducted with the GNSS SN-3803M signal simulator allowing us to determine the state of operability of the transport complex with a reduction in the number of the working constellation satellites.
Keywords: unmanned aerial vehicle (UAV), on-board navigation system, GNSS, trajectory accuracy.
