In satellite configuration design, blinding analysis should be made to determine whether the optical sensor will fail due to being blinded by components of the satellite. A blinding analysis tool for satellite optical sensors was developed to replace the inefficient way of manual analysis. The design rationale and functions of the tool were presented. It was based on the 3D CAD software, SolidWorks, and embedded in it by means of DLL (dynamic link library). It was a plug-in customized with the SolidWorks API and Visual Basic, and with knowledge of computer graphics. It can treat with satellite assembly in SolidWorks to carry on the following blinding analysis functions: setting attributes for sensor optical cone, painting blinding chart, and computing blinding ratio.
