摘要
对全球卫星定位系统的DOP因子进行了分析。对GPS/GLONASS共用系统的可用性和PDOP因子进行了理论分析和软件仿真,对星座的定位特性进行了评估。分析结果表明,GPS/GLONASS共用系统相对于单一的GPS系统在可用性和PDOP因子方面都有很大的改善,从而可以进一步改善定位精度,这就为GPS/GLONASS组合导航的进一步研究和应用奠定了基础。
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.
