The invention discloses a method for calculating an expected attitude trajectory when a satellite observes a space target. The method comprises the following steps: S1, calculating an inertial vector of the satellite pointing to the target and the representation of the inertial vector in an orbital coordinate system; s2, calculating expected attitudes of other two axes except the optical axis direction by using optical axis pointing constraint; and S3, calculating an expected attitude in the optical axis direction by using the view field constraint. The method is suitable for the situation that the camera view field has requirements in the target observation process, and the expected attitude under the constraint of the specific view field can be obtained.
本发明公开了一种卫星观测空间目标时的期望姿态轨迹计算方法,包括以下步骤:步骤S1、计算卫星指向目标的惯性矢量及其在轨道坐标系的表示;步骤S2、利用光轴指向约束计算除光轴方向外其他两轴的期望姿态;步骤S3、利用视场约束计算光轴方向的期望姿态。本发明适用于目标观测过程中对相机视场存在要求的情况,可以获知特定视场约束下的期望姿态。
