摘　　要：针对星基Argo数据收集系统(data collection system,DCS)浮漂多普勒位置反演的应用需求,通过对地球表面约束、数字高程约束两种模型在实际应用中的收敛性能分析,给出面向海洋特色应用的缺省高度约束的位置反演算法,并建立了算法精度分析评估模型。基于此模型实现了对观测样本特征、星上时标精度等浮标采集位置反演影响因子的有效分析,从而为星基Argo数据采集系统下行数据位置反演算法优化、星上载荷设计优化及大星基信息采集系统建设提供理论参考。To meet the practical application requirements of the floating Doppler position inversion of a space-based Argo data collection system(DCS)using the convergence performance analysis of two models of earth surface and digital elevation constraints,this study proposes a position inversion algorithm with a default height constraint for marine characteristic applications.Moreover,an algorithm accuracy analysis and an evaluation model are established.Based on this model,the influencing factors of the data retrieval of buoys—including the observation sample characteristics and accuracy of the time scale on the satellite—are effectively analyzed.The results provide a theoretical reference for the algorithm optimization of the downlink data position inversion,design optimization of onboard loads,and construction of a large satellite-based information acquisition system.
