摘　　要：轨迹发生器为捷联惯导算法程序提供仿真测试数据。选定理想轨迹,用捷联惯导原理逆向解算出元件输出,引入误差后输入捷联惯导算法程序,得到解算轨迹。针对传统捷联惯导轨迹发生器引入误差不全面的问题,提出全面考虑误差的新型轨迹发生器。用元件真实数据分析出各项误差,将各项误差引入理想元件输出,得到较传统捷联惯导轨迹发生器更加接近真实情况的轨迹数据。仿真结果表明,新型轨迹发生器较传统轨迹发生器更加接近真实情况,是一种可靠的捷联惯导轨迹发生器。As the traditional strap-down inertial navigation trajectory generators have some problems such as only considering white noise or not in all round way when importing error, a new trajectory generator which takes a full account of error is put forward. Using trajectory generator to create ideal output, importing the error which is modeled from real devices, the final outputs which are much close to the reality has been got. the traditional trajectory generators and the new one are compared for analyzing.The result demonstrates that the new trajectory generator is more reliable and practical than the traditional one.
