    • Light detector module for star tracking, comprising at least two detectors (1,1'), each mounted at the bottom of a protection case (2,2'), the axes (3,3') of which protection cases being located within a common plane Pl and extending in a first angle area Al between a first inclination angle α to a second inclination angle β. The end of each protection case is truncated by mainly of at least nearby parallel truncation planes P2, P2' which are mainly perpendicular to said plane Pl and which, moreover, incline, for each protection case, under a third inclination angle γ being within said first angle area Al. preferably, the third inclination angle γ is between a second angle area A2, mainly extending around the value (α + β) / 2, e.g. between the value ((α + β) / 2) - 15°) and ((α + β) / 2) + 15°), or to provide module symmetry equal to (α + β) / 2. Preferably, the end of each protection case are truncated by nearby parallel truncation planes P2, P2', however, having a small positive deviation angle ε e.g. between 0 and 5°.
    • 用于星形跟踪的光检测器模块,包括至少两个检测器(1,1'),每个检测器(1,1')安装在保护壳体(2,2')的底部,保护壳体位于其内的轴线(3,3') 公共平面P1,并且在第一倾斜角度α到第二倾斜角度β之间的第一角度区域A1中延伸。 每个保护壳的端部主要由主要垂直于所述平面P1的至少附近的平行截头平面P2,P2'截断,并且此外,对于每个保护壳体,在第三倾斜角度θ处倾斜。 在所述第一角度区域A1内。 优选地,第三倾斜角θ 在第二角度区域A2之间,主要围绕值(a +β)/ 2延伸,例如。 ((a +ß)/ 2)-15°)和((a +ß)/ 2)+ 15°之间),或提供等于(a +ß)/ 2的模块对称性。 每个保护壳体由附近的平行截头平面P2,P2'截断,然而,具有小的正偏移角e,例如, 介于0和5°之间。
