| Abstract: | The loose integrated system based on HRG and star sensor fail to work normally under the condition of few stars.In order to solve this problem, a new data fusion using the algorithm of star map recognition is proposed, which can make sure the integrated attitude measurement system can work properly even the number of observed stars is less than 3 |
