摘　　要：我国传统地球静止轨道(GEO)卫星外热流经验已不满足当前地球同步轨道(GSO)通信卫星热设计需求。为此,文章针对小倾角GSO卫星和倾斜地球同步轨道(IGSO)卫星开展姿态控制策略、轨道倾角及升交点赤经对卫星外热流的影响规律研究。分析结果表明:对于小倾角GSO卫星,姿态与轨道升交点赤经对南北面外热流有不容忽视的影响;对采用实时偏航控制的IGSO通信卫星,应关注太阳翼红外热流对卫星本体的影响。The external heat flux experience of traditional GEO(geostationary orbit)satellites in China no longer meets the current thermal design requirements of GSO(geosynchronous orbit)communications satellites.Therefore,the research on the influence of attitude control strategy,orbit inclination and right ascension of ascending node on the external heat flux of small inclination GSO and IGSO(inclined geosynchronous orbit)satellites are conducted in this paper.The analysis results indicate that for small inclination GSO satellites,the attitude and right ascension of ascending node have an significant impact on the external heat flux outside the north and south planes.For IGSO satellites using real-time yaw control,attention should be paid to the impact of solar wing infrared heat flux on the satellite body.
