|
摘要
机载导航设备的性能测试需要精准的飞行轨迹数据来搭建测试环境。针对北斗接收机的测试需求,考虑航迹约束及飞机基本性能约束,采用类迭代的坐标变换方法,设计开发了飞行轨迹仿真生成器。该飞行轨迹仿真生成器可产生飞机从起飞至降落的整个基于实际飞行程序的轨迹数据和姿态参数,并将数据实时输出及显示。利用该飞行轨迹仿真生成器仿真产生了从北京首都国际机场至广州白云国际机场的全部飞行轨迹仿真数据,仿真结果表明,该飞行轨迹仿真生成器产生的航迹参数精度高,数据切实有效,可用于北斗接收机测试环境的搭建。
The airborne navigation equipment needs accurate flight trajectory data to test its performance. According to the requirements of the Beidou receivers, considering the constraint of trajectory and flight performance, a flight trajectory generator is designed using iteration like method. The flight trajectory generator can generate the whole trajectory data and the flight parameters of the aircraft based on the actual flight procedures, and display the data and parameters in real time. The whole flight trajectory simulation data from Beijing International Capital Airport to Guangzhou Baiyun International Airport is generated. The result shows that the flight trajectory generator can generate accurate and effective flight trajectory data, and can be used to build the test environments for the Beidou receivers.
