Abstract:
Effect of systematic error on Position Dilution of Precision(PDOP)of geometry orbit determination for Geostationary Earth Orbit(GEO)satellite was discussed. Firstly, the fundamental principle of classical geometry orbit determination was reviewed; secondly, the formula calculating PDOP was deduced by the method of geometry orbit determination with systematic error; thirdly, PDOP with multi systematic errors was computed by simulated data from five tracking stations. The result showed that the influence of systematic errors on PDOP of geometry orbit determination for GEO satellite was significant; the influence could be efficiently weakened with the method of geometry orbit determination with systematic error; compared with the tracking stations selected only in China, overseas tracking stations selected could weaken the influence of systematic errors on PDOP more efficiently.
