为了全面分析各因素对星光折射间接敏感地平定位精度的影响, 在分析星光折射定位模型各类误差来源及其误差特性的基础上, 建立了大气密度、 折射角、 密度标尺高度与星光折射间接敏感地平定位精度之间的误差传递模型, 并利用MSIS(质谱非相干散射模式)大气数据对这些误差传递模型进行了不同条件的验证与分析, 为间接地平定位法的误差定量分析及工程应用提供了参考.%In order to analyze the influence of various factors on the accuracy of stellar refraction indirect horizon sensing postioning comprehensively, on the basis of analyzing a variety of error sources and error characteristics of the stellar refraction positioning model, an error propagation model between atmospheric density, starlight refraction angle, density scale altitude and the accuracy of stellar refraction indirect horizon sensing positioning is established, and this error propagation model is validated and analyzed by using MSIS (mass spectral incoherent scattering model) atmospheric data.It provides the references for error quantitative analysis and engineering application of indirect horizon sensing positioning method.
