摘要
基于北斗系统和GPS实测数据,分析了BDS单系统与BDS/GPS组合系统在亚太地区的定位精度.结果表明,BDS单系统水平方向的定位精度可达2m,高程方向定位精度可达6m,可满足导航用户定位需求.同时,BDS/GPS组合系统定位精度优于BDS单系统,能提高导航用户定位的可靠性与可用性.
The positioning accuracy of single BDS system and BDS / GPS integrated system in the Asia-Pacific region are analyzed based on Beidou system（ BDS） and GPS measurements. Results indicate that the horizontal and vertical positioning accuracy of BDS system can achieve 2m and 6m,respectively,which can meet the demand of BDS navigation users. The positioning accuracy of BDS / GPS integrated system is superior to single BDS system.BDS / GPS integrated system increases the number of visible satellites,and also improves the reliability and availability of the navigation user.
