摘　　要：提出了一种基于无线测定卫星业务(RDSS)系统观测数据提取电离层TEC参数的方法,利用此方法计算分析了2006年5月地面中心地区电离层垂向TEC的日变化趋势.研究结果表明,利用RDSS系统观测数据提取的电离层垂向TEC,在北京时间每日凌晨0400时左右达到最小值,在午后1400时左右达到最大值,符合电离层TEC参数受太阳活动影响较大的物理规律.结果说明研究方法是可行且有效的,文章还对可能存在的误差进行了探讨.In this paper, a method of calculating the ionosphere TEC （Total Electron Content） is proposed using RDSS （Radio Determination Satellite Service） System observation data, and gained the ionosphere vertical TEC and its diurnal variation tendency of center station region using one month＇s data. The result indicates that the ionosphere TEC derived from the RDSS observational data touch bottom at about 4 o＇clock and come to a peak at 14 o＇clock （Beijing Time）, which matches the physical rule that the ionosphere is affected by the solar zenith angle. Using the calculating method introduced in this paper, the TEC of ionosphere can be properly derived, and the trend of TEC would be properly got. This method is feasible and valid. Some errors, which might exist, are also disassed in this paper.
