【摘要】 GPS与GLONASS系统的联合应用有利于提高单点定位的精度及稳定性。文中简要介绍GPS/GLONASS等导航系统,讨论GPS/GLONASS组合单点定位算法,并采用拉萨IGS站的观测数据计算分析GPS与GLONASS伪距单系统以及组合系统单点定位精度。结果表明组合定位精度优于单系统定位。更多还原

【Abstract】 Integrated GPS/GLONASS systems are used to improve the accuracy and reliability of Single Point Positioning(SPP).In this paper,the GPS/GLONASS and other navigation systems are first briefly introduced.Then,the SPP algorithm with integrated GPS/GLONASS systems is investigated,and the numerical experiment is performed by using the real data of LHAZ IGS station.The result indicates that the SPP accuracy of integrated systems is better than that of individual system.更多还原
