GNSS天线相位中心模型的演变

摘要

Introduced the basic concept with the definition for the GNSS antenna phase center correcting,analyzed the correcting formula of phase center offsets（PCO） and phase center variations（PCV）,and the evolvement of GNSS antenna phase center models from relative antenna phase center model to absolute antenna phase center model,finally combinative softwares to phase center correct realizes method proceeds introduction.%介绍了GNSS天线相位中心改正的基本概念和定义,分析了相位中心偏差（PCO）和变化（PCV）的改正公式,以及天线相位中心改正从相对相位中心模型到绝对相位中心模型的演变,最后结合软件对相位中心改正的实现方法进行了介绍。
