| 摘 要： | 在高精度GPS卫星导航数据处理中，卫星和接收机天线的PCO和PCV作为重要的误差来源之一，必须予以改正。本文从高精度基线解算入手，分析了卫星和接收机天线PCO和PCV中各项对高精度基线解算结果的影响。试验结果表明，接收机天线PCO、PCV对长基线或超长基线在各分量方向或长度上的影响最大可达到101 mm。卫星天线PCO、PCV对长基线在各分量方向或长度上的影响在毫米水平，最大不超过4 mm；对超长基线在各分量方向或长度上的影响最大可达到40 mm。

| Abstract: | As one significant error source,the receiver antenna and GPS satellite antenna PCO/PCV must be corrected in high accuracy data processing.In this paper,the influence of receiver antenna and GPS satellite antenna PCO/PCV is analyzed for baseline processing.The result shows that the effects of receiver antenna PCO/PCV for long and very long baseline in components and length can reach 101mm.The effects of satellite antenna PCO/PCV for long baseline in components and length are in millimeter level,the maximum is less than 4mm,for very long baseline,the effects in components and length can reach 40mm. |
