摘　　要：基于MEMS陀螺仪和加速度计的工作特性,介绍捷联惯性导航系统姿态解算方法,通过对器件的姿态、速度、位置进行更新算法,之后利用载体运动得来的数据用Matlab捷联惯性导航程序进行仿真,再利用与组合导航程序进行整体对比。试验结果表明,论文方法能较为准确分析载体各参数信息,具有一定参考和使用价值。Based on the working characteristics of MEMS gyroscope and accelerometer,strapdown inertial navigation system attitude calculation methods are introduced.By updating the device's attitude,speed and position,the data obtained from the carrier motion is used to use Matlab strapdown inertial.The navigation program is simulated,and then the overall comparison with the inte-grated navigation program is carried out.The test results show that the method in this paper can accurately analyze the information of each parameter of the carrier,and has certain reference and application value.
