| 摘 要： | 首先介绍了新型深组合GPS/INS系统原理图及组合导航滤波算法。在该算法中，组合卡尔曼滤波器除完成INS误差及GPS接收机时钟误差的估计外，还参与了GPS码跟踪，即完成传统码跟踪环中环路滤波器的功能。采用自适应码跟踪误差估计器补偿组合卡尔曼滤波器测量值中的相关分量，从而消除了传统组合中不稳定的主要根源。然后进行了计算机仿真计算，仿真结果表明，新型深组合GPS/INS导航算法适用于机动性较高的载体。

| Abstract: | In this paper, the navigation filtering method of new tight GPS/INS integration system is presented, its principle frame figure is presented. Integrated Kalman filter is used estimations of INS's error and GPS receiver clock's error. It is used code tracking loop in order to function of loop filter in tradition code tracking loop. A adaptive code tracing error estimator is used to compensate for correlation component of integrated Kalman filter' measure value. The computer simulation is done. The results show that the navigation filtering method of new tight GPS/INS integration system is adapted for high dynamic carrier. |
