A tracking and pointing attitude maneuvering path planning method based on a normal vector belongs to the technical field of spacecraft attitude control, and comprises the following steps: at any moment in a tracking and pointing maneuvering process, setting a camera optical axis to align a target, setting a satellite body axis direction vertical to the camera optical axis according to maneuvering capability and direction requirements, the setting basis is that the body shaft is in the set normal vector direction; the set normal vector direction is determined according to the tracking and aiming task and comprises four conditions, namely data transmission protection, energy protection, maneuver protection and imaging protection. According to the method, the normal vector of the plane is formed by applying the target pointing and the ground pointing, so that the target attitude setting during antenna ground data transmission is maintained as much as possible while tracking and pointing are realized.

    一种基于法向量的跟瞄姿态机动路径规划方法,属于航天器姿态控制技术领域,包括:在跟瞄机动过程中的任意时刻,设置相机光轴对准目标,与相机光轴垂直的卫星本体轴指向根据机动能力和指向需求设定,设定依据为本体轴在设定的法向量方向上;所述设定法向量方向根据跟瞄任务确定,包括四种情况,分别为保数传、保能源、保机动、保成像。本发明通过应用目标指向和对地指向构成平面的法向量,实现了跟瞄同时尽可能维持天线对地数据传输时的目标姿态设置。
