北斗二代在中国及周边海域的定位分析

摘要

High-performance Beidou-2/GPS receiver is used to acquire Beidou-2 and GPS data at the end of 2011.Then,the navigation and positioning features are analyzed under different movement modes,different regions and different satellite navigation systems.The results show that the separate Beidou-2 navigation system can meet the demand of standard positioning in China and surrounding seas.%使用高性能北斗/GPS接收机,于2011年底采集了实测的北斗和GPS数据,分析了不同运动状态下、不同区域、不同卫星导航系统的导航定位特征.结果表明,单独的北斗二代导航系统可以胜任中国及周边海域的标准定位需求.
