某型机在飞行训练过程中，进近段的二维相对姿态数据对于该型机安全着陆有着至关重要的作用。基于无线网络电台的双向数据传输系统能够实时获取进近段飞机相对理想着陆点的水平、垂直相对位置数据。通过上行链路上传着陆点的姿态数据，下行链路实时下传动动差分后的差分数据,最后在中心控制站进行二次数据处理。该技术获得的进近段二维相对姿态精度达到厘米级，满足飞行训练的需求。同时结合飞机显控数据以及视景图，以多角化动态关联的方式将实时获取的姿态数据等呈现给指挥员，更好地辅助指挥员进行着陆指挥工作。

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.
