GPS/INS integration systems are widely used in different fields. Since GPS receiver carrier loop has lost lock during maneuver,the velocity aiding signal of code loop is derived from the inertial navigation system. Because of the correlation between the pseudorange measurement error and the inertial velocity etror,it will make the integration system operation instable. On the basis of GPS receiver code loop operation characteristics, the code loop tracking error is considered in the Kalman filter.Optimal navigation satellites are selected in real time by a GPS simulator. The navigation performance of a GPS/SINS integration system is analyzed during the airplane maneuver.The simulation results show that the code loop operates in the tracking state,the integration system operates normally and stably,and the navigation accuracy of the system is evidently improved when the correlanon between the pseudo-range measurement error and the inertial velocity error is eliminated.

GPS/惯性导航组合系统目前正得到越来越广泛的应用,但GPS接收机载波环失锁时,码环的速率辅助信息来自惯导系统。由于惯性速度的不精确性及伪距测量误差和它之间的相关性,将可能导致组合系统工作的不稳定。本文根据码环的工作特性,在组合系统卡尔曼滤波器中考虑了码环的跟踪误差,利用GPS星座仿真器实时选择最佳导航星,用协方差法分析了飞机机动飞行时GPS/捷联惯导组合系统的导航性能。结果表明,GPS/捷联惯导组合系统中,若消除了伪距测量误差与惯性速度误差之间的相关性,将可较显著地提高导航系统的导航精度,并保证了码环处于跟踪状态,使组合系统能正常稳定地工作。

The error model of the GPS receiver code loop can be expressed as the Markovian process. When GPS receiver carrier loop loses lock,the velocity aiding signal of the code loop is derived from the inertial navigation system. Considered or ignored the code loop tracking errors in the GPS/SINS integration system error state equations,the Kalman filter is used to analyze the integration system navigation performance in this paper.

The error model of the GPS receiver code loop can be expressed as the Markovian process. When GPS receiver carrier loop loses lock,the velocity aiding signal of the code loop is derived from the inertial navigation system. Considered or ignored the code loop tracking errors in the GPS/SINS integration system error state equations,the Kalman filter is used to analyze the integration system navigation performance in this paper. The receiver code loop tracking performance influenced by the correlation between the ptseudo range measurement errors and the inertial velocity errors is also approached.The simulation results show that the aeroplane maneuver and the changement of the optimal navigation satellites have an influence on the GPS receivercode loop operating stability.

GPS接收机码环跟踪回路的误差模型一般可用一阶马尔可夫过程来近似,且当接收机载波环路失锁时,码环的速率辅助信息来自惯性导航系统的惯性速度。鉴于此,本文对GPS/SINS组合系统误差状态方程中考虑或忽视码环跟踪误差的两种情况,用卡尔曼滤波器对系统性能进行研究,并探讨了飞机机动飞行时伪距测量误差与惯性速度误差之间的相关性对接收机码环跟踪性能的影响。结果表明,飞机机动及GPS最佳导航星在飞机运动过程中的变化对GPS接收机码环的工作稳定性都有一定的影响。

The principle of the decorrelated pseudo range approach is presented. A weighted mean tracking error estimator is designed to estimate the GPS receiver code loop tracking error. Compared with the results from the uncorrected pseudo range measurements, the decorrelated pseudo range approach can reduce the integration system navigation errors, and improve the system navigation accuracy.
