【摘要】：通过不同的方案设计对中国陆态网测站进行解算,研究电离层高阶项延迟对测站坐标和接收机钟差的影响,并分析在不同地磁模型下的影响差异。结果表明,在太阳活动较为活跃时,电离层高阶项延迟对陆态网测站垂向坐标的影响能达到1.2cm,对接收机钟差的影响接近4.4mm;不同地磁模型下电离层高阶项延迟的影响很小。还分析了纬度、基线方向与长度对电离层高阶项延迟的影响。
[Abstract]:The effect of ionospheric higher-order term delay on the station coordinates and receiver clock difference is studied through different scheme design. The results show that the effect of ionospheric high-order term delay on the station coordinates and receiver clock difference under different geomagnetic models is analyzed. When the solar activity is active, the influence of ionospheric higher-order term delay on the vertical coordinates of land-based network stations can reach 1.2 cm, and the influence on receiver clock error is nearly 4.4 mm, and the effect of ionospheric higher-order term delay on different geomagnetic models is very small. The latitude is also analyzed. The effect of baseline direction and length on ionospheric higher-order delay.
