面向机载捷联惯导系统的设计与验证需要,设计由惯性导航信息源、数据处理、滤波器、导航算法和初始对准等信号仿真器组成的捷联惯导数字仿真系统,并建立相应的性能评价指标体系,评价数据处理、信号滤波、导航解算和初始对准滤波等算法的有效性。最后,建立了捷联惯导数字仿真系统的综合评价模型。
For the design and verification of on-board SINS, an SINS digital simulation system composed of inertial navigation information source, data processing, filter, navigation algorithm and initial alignment signal simulator is designed and correspondingly established Performance evaluation index system to evaluate the effectiveness of the algorithms such as data processing, signal filtering, navigation solution and initial alignment filtering. Finally, a comprehensive evaluation model of SINS digital simulation system is established.
