一种GEO轨道卫星的星敏感器热控布局方法
摘要：
一种GEO轨道卫星的星敏感器热控布局方法，步骤为：（A）在卫星舱板西板的外表面的左下角和右下角分别安装ASTRO10星敏感器支架（2）和APS星敏感器支架（3），安装面之间安装隔热垫；（B）将ASTRO10星敏感器（5）安装在ASTRO10星敏感器支架（2）上，将APS星敏感器（6）安装在APS星敏感器支架（3）上，安装面之间涂抹导热硅脂；（C）在ASTRO10星敏感器（5）和ASTRO10星敏感器支架（2）的外侧套装ASTRO10星敏感器热控舱（1），在APS星敏感器（6）和APS星敏感器支架（3）的外侧套装APS星敏感器热控舱（4），安装面之间安装隔热垫；（D）在两个热控舱的外表面上安装铝板，然后在铝板上粘贴二次表面镜。
摘要（英）：

A thermal control distribution method for star sensors of a GEO (geostationary earth orbit) satellite comprises the following steps of (A) respectively mounting an ASTRO10 star sensor support (2) and an APS star sensor support (3) at a left lower corner and a right lower corner of an outer surface of a west board of a deck of the satellite, and mounting a thermal insulation pad between mounting surfaces; (B) mounting an ASTRO10 star sensor (5) on the ASTRO10 star sensor support (2), mounting an APS star sensor (6) on the APS star sensor support (3), and coating heat-conduction silicon grease between mounting surfaces; (C) sleeving an ASTRO10 star sensor thermal control cabin (1) on the outer sides of the ASTRO10 star sensor (5) and the ASTRO10 star sensor support (2), sleeving an APS star sensor thermal control cabin (4) on the outer sides of the APS star sensor (6) and the APS star sensor support (3), and mounting a thermal insulation pad between mounting surfaces; and (D) mounting aluminum plates on the outer surfaces of the two thermal control cabins, and then adhering secondary surface mirrors to the aluminum plates.
