摘要
针对传统的卫星在轨定标方法存在的局限性以及适用范围不足等问题,提出了一种新的基于浮空平台的在轨定标方法,即利用浮空平台搭载镜面阵列,并用后者反射太阳辐射来对卫星进行定标。建立了基于浮空平台的在轨定标模型,并对其进行了分析。结果表明,与传统的在轨定标方法相比,该方法具有大气路径短、波段适用范围广和定标精度高等优势。
Because of the limitation and limited usable range of traditional satellite in-orbit calibration methods, a new in-orbit calibration method based on an aerostat is proposed. In the method, the satellite is calibrated via the solar radiation reflected by an aerostat-borne mirror array. An in-orbit calibration model based on an aerostat is established and analyzed. The result shows that compared with the traditional in-orbit calibration methods, this method has the advantages of short atmospheric path, wide wavelength range and high calibration precision.
