摘要
介绍了GPS天线相位中心改化原理,实现了天线相位中心改化算法。用GPAS软件进行实验数据解算,比较分析天线相位中心改正对静态基线解算结果的影响,实验结果表明天线高的影响必须改正,相位中心偏差(PCO)对定位结果有厘米级的影响,相位中心变化(PCV)的影响在毫米级。
The principle of correcting antenna phase center is introduced in this paper.With reference to the GAMIT software , antenna phase center correction algorithm is realized based on the GPAS software which is independent research and development by Chinese Academy of Surveying and Mapping.A sample is computed to consider the impact of the antenna phase center corrections on the solution of static baseline.The results show that the antenna height impact must be corrected , the impact of PCO on positioning results is in centimeter level , the impact of the PCV is in millimeter level.
