The Associated Modeling and Precision Analysis of Spatial States and the Inter-Satellite Baseline of Formation Flying Satellites

The inter-satellite baseline plays a vital role in the formation flying satellites missions. Based on the relation between the spatial states and the inter-satellite baseline, this paper erects a model to associate these two kinds of parameters. The error propagation relations are deduced in detail, which are described by the precision influence factors and error propagation matrices. Simulations are also carried out to show the baseline determination precision in some certain scenarios.
