Embodiment Construction
[0017] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0018] As shown in Figure 1, the working process of the present invention is as follows:
[0019] (1) The user calculates the angle at which the entire star needs to be swayed according to the observation target. For example, the current attitude angle of the satellite is 0° (that is, the roll angle, pitch angle, and yaw angle are all 0°), and the satellite is required to swing 20° to the east. (That is, the roll angle is 20°, the pitch angle and the yaw angle are both 0°, that is, the target attitude). After receiving the side swing command, the on-board control computer uses quaternion to describe the satellite attitude, and the satellite attitude angle is converted into a quaternion according to the following formula:
[0020]
[0021] In the formula: , θ, ψ are the roll angle (ie roll angle), pitch angle and yaw angle of the satellite, ...
