| Abstract: | In order to improve the measuring-speed and precision of star sensor, cutting algorithm which is used far and wide currently in the field of physical geography is adopted first in the area of star map identification. Using this algorithm to identify star map, the simulation results show that compared with the current star map identification algorithm, this algorithm presented has the advantages of real time properties and robust; it only needs a small content database and searches data rapidly. |
