Abstract

An alternative zero-difference orbit determination approach is used to establish the corresponding mathematic model and develop the orbit determination software of low earth orbit satellite with satellite-based GPS. and effects of main error sources on orbit determination are studied. Also orbit determination and prediction precision attained with this method are studied deeply. Simulated calculation reveals that this method can be used in precise orbit determination.
