Abstract

This paper analyzes the DOP (Dilution of Precision) factor of global positioning systems. Our study includes theoretical analysis and software simulation of combined GPS/GLONASS availability and PDOP. The analysis results revealed that by comparison to the stand alone GPS system, the combined GPS/GLONASS system improves availability and PDOD values for positioning, therefore further improves the positioning accuracy. It advances the further research and application of combined GPS/GLONASS navigation.
