摘要：

为了在太阳同步轨道卫星上,实现太阳辐射监测仪对太阳辐射的跟踪测量,提出了一种卫星本体坐标系上太阳方位的计算方法.首先,采用巴黎天文台的VSOP87理论计算太阳在地心惯性坐标系下的太阳方位;然后,通过坐标变换转换到卫星本体坐标系上,实现了太阳方位的计算;最后,利用拟平均根数法生成卫星瞬时轨道根数,模拟计算太阳方位的计算精度.该方法对卫星本体坐标系上太阳方位的计算精度优于0.19°,满足实际跟踪精度的要求.

Abstract:

A method for calculation of the sun’s location in the satellite’s body coordinate system is proposed in order to measure the solar irradiance using solar irradiance absolute radiometer on the sun synchronous orbit satellite. First, the sun’s location in the inertial coordinate system is calculated using the VSOP87 theory. Then, the sun’s location in the satellite’s body coordinate system is obtained by coordinate transformation. Finally, the satellite’s instantaneous orbital elements of high accuracy are generated based on the mean orbital elements to simulate the precision for calculation of the sun’s location. The simulation shows that the accuracy for the calculation of the sun’s location is within 0.19°.
