摘    要:
首先针对GPS时钟漂移,推导了计算位置误差的表达式,然后对GPS/BD2组合系统的时钟漂移进行了分析和修正,并利用模拟信号源提供的信号进行了仿真.结果表明:经过时钟漂移修正后,定位精度有了一定的提高,验证了仿真结果.

关 键 词:时钟漂移  GPS/BD2  定位精度

Abstract:
In terms of the time excursion of GPS,a position error expression is deduced.Then,the time excursion of GPS/BD2 combined system is analyzed,corrected and simulated by using signals from the simulation signal source.The results demonstrate that the positioning accuracy is improved after correcting the time excursion.
Keywords:time excursion  global positioning system/BeiDou2(GPS/BD2)  positioning accuracy
