Abstract:

To analyze the effect of surface optical parameters on some kind of navigation satellite(simply named B navigation satellite or B satellite in the following part), firstly an analytical SRP(solar radiation pressure) model for B satellite referring to GPS SRP modeling method is constructed by combining features of structure, control and orbit of B satellite. Then the constructed SRP model is used to analyze the effect of change in surface optical parameters. At last, the constructed model is used to predict orbit and compare the prediction results with precise ephemeris to prove our model and analyze the effect of surface optical parameters on orbit prediction.

Key words: Solar radiation pressure model, Box-Wing model, Surface optical parameter, Orbit prediction
