Star sensor is the high precision optical sensor which is widely used in attitude measurement of the spacecraft nowadays. Low volume
low power consumption
high precision and high update rate are common features of the development of star sensor. In this paper
the composition of update time is presented
and the parallel processing mechanisms using pipelining method are analyzed emphatically. In addition
the sequential mode
two and three cycles pipelining mode are realized on the engineering prototype and the comparison of three actual realization results are given. Finally
multi-head star sensor method and software interpolation method for increasing update rate of the star sensor are introduced.
