摘　　要：分析了GNSS电离层层析算法,提出在电离层层析过程中引入一些条件关系来提高层析精度和可靠性,并利用IGS站提供的观测数据对2010-08-03欧洲区域进行了电离层图像重构,证明了本文方法的可行性。As an important part in the near Earth space environment, the ionosphere activity is closely related to human survival and development and has a significant impact for production and life of human beings. At present, most studies are based on the ionosphere iono spheric total electron content （TEC）. It can only reflect the level of the ionosphere structure, but cannot reflect the vertical structure of the ionosphere. Computerized ionospheric tomography（CIT） technology based on GNSS is most convenient and effective. Analyzing CIT techniques, some conditions are proposed to prove its accuracy and reliability. Using observation data provided by IGS stations on August 3, 2010, an ionospheric image of the European region is reconstructed. It shows the feasibility of this method.
