| 摘 要： | 通过全球导航卫星（GNSS）系统获取对流层天顶延迟对于气象和电波折射修正具有重要应用价值。利用自主研发的静态精密单点定位软件CRPPP，基于国际GNSS地球动力学服务局（IGS）发布的北斗系统（BDS）精密星历和精密钟差，给出了BDS估算天顶延迟结果。以IGS发布的全球定位系统（GPS）结果为参考对比，BDS估算天顶延迟结果平均偏差优于5mm，均方根误差（rms）优于2．3cm．同时，给出了西沙地区GPS与BDS估计结果，结果表明：利用北斗系统估计的对流层天顶延迟精度与GPS相当。

| Abstract: | It is of great application value for weather and wave refraction correction to obtain tropospheric zenith delay through GNSS （Global Navigation Satellite System）. Based on BDS（Beidou System） precise ephemeris and precision clock released on IGS（International GNSS Service）, the zenith delay results are given, estimated by CRPPP which is a self developedstatic precise point positioning software. Compared with GPS（Global Positioning System） ,the mean deviation and RMS of the results estimated by BDS are respectively better than 5 mm and 2.3 mm. At the same time,the results in Xisha area respeclively estimated by GPS and BDS are given,which shows that the accuracy of tropospheric zenith delay between them is similar. |
