    摘要:

    首先,对不同的 GPS/SINS组合模式进行了分析;在此基础上针对基于伪距、伪距率的紧组合导航系统进行研究,建立了系统的状态方程和量测方程,并用 Matlab进行了仿真实现。在系统的仿真实现中,由于很难获得全面真实的导航飞行轨迹数据,文章采用一种纯数学形式的解析方法来产生飞行轨迹数据,因而系统的仿真包括 3部分:轨迹发生器、GPS仿真子系统、SINS仿真子系统。仿真结果表明,GPS/SINS紧组合导航系统能够有效地提高系统的导航精度,用纯数学形式的解析方法来产生飞行轨迹数据是可行的、有效的。

    Abstract:

    First, the different GPS/SINS combined models is analyzed. On this basis, the tightly integrated navigation sys.tem based on pseudo-range and pseudo-range rate was studied, and the system state equation and measurement equationwere established and a simulation was made with Matlab. In the simulation of the system comprehensive and actual flighttrack data was hardly received, so in this paper a pure mathematical form analytical method was used to generate flightpath data. Therefore, the simulation system consisted of three parts, such as the trajectory generator, GPS simulation sub.system, SINS simulation subsystem. Simulation results show that GPS/SINS tightly integrated navigation system could ef.fectively improve the navigation accuracy and using applying pure mathematical form analytical method to generate flightpath data was feasible and valid.
