| 摘 要： | 针对惯性导航系统(INS)存在积累误差的缺陷,运用GPS姿态测量辅助修正方法对INS误差进行补偿来进一步提高INS的定位精度.通过对INS系统可观测性进行分析,得出增加不同种类的外部导航信息观测量将有效提高INS误差修正能力的结论.研究了船用INS与GPS姿态测量系统组合的组合导航系统,并对GPS姿态测量系统信息对惯性导航系统的误差修正能力进行了仿真.仿真结果证实上述方法可有效提高INS的定位精度.

| Abstract: | The long-term accumulative error of inertial navigation system (INS) must be compensated to improve INS location precision. So the auxiliary revision method based on GPS attitude determination is presented to compensate the INS errors in this article. By the observed capability analysis of INS, adding more kinds of external navigational information the integrated navigation system can promote the capability of INS error-correction. After the establishment and research of the integrated navigation system of INS and GPS attitude determination system, the capability of INS error-correction based on GPS attitude determination is simulated. Simulations validate the effectiveness of this method to enhance INS location precision. |
