High-precision relative posture real-time measurement technology for a certain aircraft

During the flight training of one machine, the two-dimensional relative attitude data of the approach segment plays a crucial role in the safe landing of the aircraft. The two-way data transmission system based on the wireless network radio station can obtain the horizontal and vertical relative position data of the approaching aircraft relative to the ideal landing point in real time. The attitude data of the landing point is uploaded through the uplink, the differential data after the dynamic difference is driven in the downlink, and finally the secondary data processing is performed at the central control station. The two-dimensional relative attitude accuracy of the approach segment obtained by the technology reaches the centimeter level, which satisfies the requirements of flight training. At the same time, combined with the aircraft’s display control data and the visual map, the real-time acquired attitude data is presented to the commander in a multi-angled dynamic association manner, and the assistant commander is better assisted in the landing command work.
