摘要
由于实验务件限制,GPS/INS组合导航系统很难在真实空间交会对接环境中进行GPS/INS组合导航系统性能测试研究。为此,简要设计和实现了基于空间交会的GPS/INS组合导航软件仿真平台,研究了基于空间交会两航天器绝对和相对运动轨迹生成、GPS/INS组合导航系统误差建模、观测数据生成等实现方法,并通过仿真数据分析验证了这种设计方案的可行性,为进一步开展相关研究奠定了基础。
Due to the limitation of experimental conditions, it is difficult to collect practical data of integrated GPS/INS navigation system for space rendezvous and use it to test the performance of integrated navigation system. In order to resolve the problem, a simulation software of the integrated GPS/INS navigation system for space rendezvous was designed and implemented. The paper studied the following realization methods： 1） generate absolute and relative motion trajectories for the two space-rendezvous vehicles; 2） establish GPS/INS error model; and 3） generate observation data; etc.. Then based on the errors models for GPS and INS respectively, the measurement data for GPS/INS integrated navigation system are simulated. The applicability of the design method is tested and analyzed which show that the simulation software is feasible, and is useful for further studies.
