This paper presents a star/inertial platform system of star sensor installation error calibration method based on ground. Through the use of star simulator with high precision, to simulate distant stars, the star sensor on axis star point. The position coordinate measuring platform for stars and hexahedron, through coordinate conversion, and comparing them to get the installation error of star sensor in the inertial platform. The experimental results show that the method can accurately measure the installation error angle of the star sensor in the star/inertial platform system, and realize the accurate calibration of the error.
