摘要: 风云二号卫星在空间定位后,需计算出北京气象卫星地面站天线对卫星的方位、俯仰和极化角度。本文描述卫星与地面站的相对位置关系计算跟踪角度的原理,为了快速准确地找到卫星,可以利用天线运行角度规律仿真,建立天线跟踪模型,并把理论模型应用于卫星跟踪实践,应用螺旋扫描跟踪方法在工程实践中成功快速捕获风云二号新卫星。

Abstract: It is necessary to calculate the antenna azimuth, elevator and polarization angle of Beijing meteorological satellite ground station after FY-2 satellite positioning in space. This paper describes a calculation principle of tracking angle between the satellite and the ground station. An antenna tracking model is built by analyzing the motion rule of satellite movement. Using spiral scanning track successfully captured FY-2 new satellite in engineering practice.

Key words: spiral scanning, satellite capture, tracking angle calculation, antenna tracking
