| 摘 要： | 为了满足惯性导航和GNSS/INS组合导航对性能测试和算法验证的需求,提出一种简便的惯导观测数据仿真的方法,用于在室内仿真生成运动载体上的惯导器件的测量值。运用数学仿真的方法,在分析载体运动特点的基础上,给出了载体轨迹和姿态参数的计算方法,建立了惯导器件的观测数据及主要误差项的数学模型,并说明了惯导观测数据仿真方法在硬件平台上的具体实现过程。采用惯导软件接收机进行闭环测试,实验结果表明,该方法能生成正确的惯导观测数据。

| Abstract: | To satisfy the need for performance testing and algorithm verification of INS navigation and GNSS/INS integrated navigation,a simple method for INS observed data simulation is proposed to generate the measured value of INS device on moving carriers.With mathematical simulation method,the calculating algorithm of carrier orbit and attitude parameters is presented based on the analysis of carrier moving characteristics,the mathematical model of the observed data and main er-ror items of INS device are built,and the concrete process of the implementation of INS observed data simulation method on hardware platform is introduced.The INS software receiver is used for the closed-loop testing.The results indicate that the proposed method can generate the correct INS observed data. |
