【摘要】：通過不同的方案設(shè)計對中國陸態(tài)網(wǎng)測站進行解算,研究電離層高階項延遲對測站坐標(biāo)和接收機鐘差的影響,并分析在不同地磁模型下的影響差異。結(jié)果表明,在太陽活動較為活躍時,電離層高階項延遲對陸態(tài)網(wǎng)測站垂向坐標(biāo)的影響能達到1.2cm,對接收機鐘差的影響接近4.4mm;不同地磁模型下電離層高階項延遲的影響很小。還分析了緯度、基線方向與長度對電離層高階項延遲的影響。
[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.
