近地轨道卫星在轨道上接收的外来热流分以下三部份:太阳的直接辐射能、地球反射的太阳辐射能和地球的红外辐射能。欲准确计算出这三部份能量,除应知道卫星接收这三种能量的角系数外,还必须掌握有关参数——太阳常数,地球反照半和地球红外辐射强度的精确数值。本文将从卫星温控设计角度,介绍国外在测量和计算这三种参数方面的概况并提出设计中采用的数值。
The incoming heat flux received by a near-Earth-satellites orbit on orbits is divided into three parts: the direct solar radiation, the solar radiation reflected by the Earth and the infrared radiation energy of the Earth. To accurately calculate these three parts of energy, in addition to knowing the angular coefficients of the three types of energy received by the satellite, it is also necessary to know the precise values of the relevant parameters - the solar constant, the Earth’s albedo and the Earth’s infrared radiation intensity. This article from the satellite temperature control design point of view, introduces foreign survey and calculation of these three parameters in the overview and put forward the design used in the numerical.
