摘要
针对无人机捷联惯性导航系统飞行参数的采集问题,对一种基于捷联惯性导航系统的运动轨迹发生器模型设计进行了简要介绍。基于坐标系的定义,推导出坐标转换关系矩阵,进而完成无人机机动飞行过程的设定和轨迹参数的获取,对设计的轨迹发生器进行了仿真实验。通过仿真实验表明,此方法能够准确地模拟出给定的无人机飞行过程,为导航系统方案设计提供了依据。
Aiming at the problem of acquiring flight parameters of strapdown inertial navigation system(SINS) of UAV,a motion trajectory generator model based on SINS is designed and briefly introduced.Based on the definition of coordinate system,the deduction of coordinate transformation matrix is completed,and then the setting of UAV maneuvering flight process and the acquisition of trajectory parameters are completed.Finally,the simulation experiment of the designed trajectory generator is carried out.The simulation results show that this method can accurately simulate the flight process of a given UAV and provide a basis for the design of navigation system.
