Abstract: Spacecrafts usually keep a certain attitude in order that the payload onboard the S／C can remotely sense the targets of interest, and successfully get the interesting information about the targets during the flight mission. Two methods for realization of station pointing attitude are put forward. Therein, the influences of transformation matrices of different coordinate system on position of S／C are assessed. With these two methods fulfilled in S／C simultaneously, the station pointing attitude can be reliably and effectively realized.
