Efficiency of precise point positioning in Peninsular Malaysia from an ephemeris perspective.

Precise point positioning (PPP) is an absolute positioning technique that offer sub-decimeter level accuracy. The accuracy of PPP is dependent on the ephemerides used during processing. This study aims to investigate the effect of ephemerides on the accuracy of PPP in Peninsular Malaysia. PPP soluti...
