卫星联合定轨的参数化融合模型

Firstly, high precision denotation model of satellite orbit dynamics based on physics parameter model and mathematics model which associates sparse parameter representation with time sequence analysis, nonlinear semi-parametric combined observation model based on system error parameters modeling and non-parametric component denotation of model error, and combined orbit determination (COD) parameterized fusion model are established aiming at multi-satellite high precision COD based on bi-satellit
