- Abstract:
-
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.
