Apparatus for attitude determination test of star-sensor and method for display of imaginary constellation

Determining a position of the satellite to the invention compared to the three-axis satellite attitude to decide to make of the heavenly bodies registered in the database information and the measurement-specific coordinates in the inertial coordinate system relates to a test apparatus for testing the position determination of the satellites attitude determination relates to a test device in which the sensor-specific. The present invention therefor is to form the outer frame; Is slidably moved to the upper side of the frame provided, the flat-panel display device showing a virtual constellation; CCD camera provided on the lower surface of the flat display device recognizes a constellation plane may appear on the display device; At the same time as the CCD camera is fixed by using the virtual plane it may appear on the display of the constellation is detected from the CCD camera and the inertial measurement unit for computing a three axis attitude information; Is characterized in that the three-axis bearing of the CCD camera and the inertial measurement unit and the rotation shaft 3 rotates in the direction provided. Accordingly, the Rimed specific image on the CCD camera through the image processing can be used to calculate the angular distance for each stars, constellations Database, utilized by for real IMU compensation through the filter configuration and position determination algorithm completed by finding a pattern of a specific experiments, and finally by using the star sensor is effective to calculate the precise position of the satellites.
