Kinematic Precise Orbit Determination Based on Ambiguity-Fixed PPP

摘要: 在深入分析海域多源重力数据观测技术特性的基础上,提出了基于双权因子的多源数据网格化一步融合处理方法,以及基于分步平差、拟合、推估和内插相结合的多步融合处理方法,并通过实际算例验证了两种解析融合处理方法的有效性。Abstract: With the development of space-borne GPS technologies and IGS precise orbit and clock products,precise orbit determination(POD) of Low Earth Orbiters(LEOs) based on PPP technology has become a hot issue.At present,an accuracy of 3~5 cm in Radial(R),Along-track(T),Cross-track(N) components can be achieved with conventional PPP.However,the results are less precise or reliable than the double-differenced fixed solution due to the ambiguity-float solution in traditional PPP.In order to further improv...?More
