摘要(Abstract)：

针对如何有效控制、改正甚至消除不同区域与时段的电离层高阶项延迟对全球导航卫星系统定位结果产生的影响,该文选取了不同区域内有代表性的IGS基准站1999—2003年的观测数据进行解算,并详细分析了各测站坐标受高阶电离层延迟影响的规律。在此基础上,总结出测站的高阶项改正与测站区域地理位置的关系,并探究产生这种影响的原因。最后从全球的角度研究了电离层高阶项改正对基准站坐标的影响。结果表明,要获得高精度的定位结果,需要顾及高阶电离层延迟的影响,尤其是在赤道以及地球两极区域的精密定位,此外,需要顾及电离层变化活跃期的影响。

关键词(KeyWords)： 高阶电离层延迟;不同区域;不同时段;基准站坐标
