Processing of Star Catalog and Star Image,of guide stars, partition of the star catalog usually has to be done, which plays an important role in enhancing star identification and star tracking. At the early design stage of the star image processing and star identification algorithms, simulation approaches have to be taken to verify their correctness and to conduct performance evaluation.

Processing of Star Catalog and Star Image,acecraft by observing and identifying stars. Thus, star information is indispensable. The star information used by the star sensor process mainly includes the positions (right ascension and declination coordinates) and brightness of stars. Star sensor’s onboard memory can store the basic information

Rapid Star Tracking by Using Star Spot Matching Between Adjacent Frames, In the initial attitude establishment mode, star sensor identifies and establishes initial attitude by using the full-sky star image. Once the initial attitude of a spacecraft is established successfully, star sensor enters into the tracking mode. In normal conditions, star sensor works in the trac

ors were calculated at different incubation time intervals. Plotting IC. values vs. incubation time revealed three different patterns for test inhibitors that could be used to distinguish reversible and time-dependent inhibitors. IC. values of reversible inhibitors either maintained within a narrow
