| Popis: | This paper presents new method to determine and control nano-satellite attitude using star blurred images to a high accuracy, and verifies the method through simulation. The method is intended for use on Nano-JASMINE (Nano-Japan Astrometry Satellite Mission for INfrared Exploration), a nano-satellite currently underdevelopment at Intelligent Space System Laboratory (ISSL) Univ. of Tokyo in cooperation with National Astronomical Observatory of Japan (NAOJ). The mission is to measure the 3D positions of stars to an accuracy of 1.8 mas. In order to get accurate star position data, Nano-JASMINE should be stabilized to less than 740 mas/8.8 s (equivalent to 4 e-7 rad/s) accuracy during observation. Currently there are not sensors available for a nano-satellite to get accurate attitude information as is required by the mission. To solve this problem, the attitude will be determined by assessing the quality of the star image based on how blurred it appears from mission telescope. Based on simulation results, the paper concludes that the use of star blurred image data to determine to control attitude is a feasible method for use on the Nano-JASMINE mission. 資料番号: AA0063718005 |
