摘　　要：针对姿态实时测量解算的需求,设计了基于DSP的运动体姿态实时解算系统的整体方案,并就方案中涉及的捷联算法、初始对准及修正算法、姿态角扩展方法做了比较详尽的分析。同时通过采用实际MIMU测量硬件对系统进行了初步验证实验,实验结果表明,算法正确,系统基本满足要求,为今后的进一步工程应用提供了研制基础。In order to satisfy the demand of real-time attitude calculation,an overall program based on DSP was put forward,and then the involved key algorithms were provided which included the strapdown algorithm,alignment and correction algorithm,and attitude angles developing method.Experiment with MIMU has been done and its results show that the method has a certain applied value.
