摘要
提出了一种模拟航迹的仿真算法,为捷联惯导算法的研究提供丰富的仿真数据。应用此算法设计模拟了一条航行轨迹,根据仿真得到的机体角速度对锥运动情况下旋转矢量优化算法的优劣进行测试,证明了航迹仿真对捷联惯导算法研究的重要性;根据仿真得到的位置信息,结合某型飞机的实际航行控制方法,由导航系统构成航行轨迹并在电子地图中进行定位和航迹仿真显示,证明了方法的可行性和有效性。
A sort of simulation algorithm of trajectory was presented, which can provide abundant data for the research of algorithm of strapdown INS. A trajectory was designed applying this algorithm. The improved rotation vector algorithm in the coning motion was tested based On angular rate of air body gained from simulation, which proved that trajectory simulation was important to the research of algorithm of strapdown INS. Based on positions gained from simulation and practical navigational control mode of some type of air, the trajectory was made and it was positioned and displayed in the electronic map, which proved the feasibility and validity of method.
