摘　　要：采用12 m A-E天线座架的气象卫星接收系统在跟踪运行于太阳同步轨道的风云三号气象卫星时,方位角误差随着俯仰角的增大而不断增大,到天顶区域已无法满足跟踪要求。为了解决卫星站过顶盲区问题,在接收天线上增加机械倾斜第三轴,通过分析计算,提出了实用的软件处理方法。实际运行情况表明,此方法较好地解决了过顶跟踪的目标丢失问题。When tracking the FY-3 meteorological satellite in sun-synchronous orbit, the error of aximuth of the satellite reception system, which use 12 meters A-E antenna, is increased with the rising of elevation angel. In the overhead area, the reception sys- tem can not satisfy the tracking demand. In order to solve the zenith blinde zone problem, the mechanical tilt third axi is added in the antenna, and designed tilt overhead tracking control software according to theoretical analysis and calculation. Practical experi- ment shows that this method has solved the tracking zenithal targets effectively.
