Abstract: Pseudo range measure error oscillation phenomenon was discovered in BDS GEO/IGSO satellites monitoring. Research on the phenomenon was made with multipath signal generation and multipath effect theory. The dynamic multipath effect of satellites including GEO, IGSO and MEO were simulated based on the construction of dynamic model of satellites and multipath mirror reflection model. Theory analysis and simulation were made on the pseudo range and carrier phase measure error caused by different dynamic multipath effect. The simulation result is similar with the measure result of practical observation, which gives a new reference for the final revelation of the reason of the range measure error oscillation phenomenon of BDS GEO and IGSO satellites.

Key words: pseudo range measure error oscillation, satellite navigation signal, multipath effect, satellite dynamic
