A four-segment trajectory planning method for active push-broom of an imaging satellite is characterized in that a planned motion trajectory is divided into an initial speed elimination segment, a point-to-point maneuvering segment, a stationary segment and an angular speed preset segment according to a time sequence, and the point-to-point maneuvering segment is divided into an acceleration sub-segment, a constant speed sub-segment and a deceleration sub-segment; angular accelerations planned by the initial speed elimination section, the angular speed preset section, the acceleration sub-section and the deceleration sub-section are sine functions; then determining the time point of each section and the target attitude quaternion, the target angular velocity and the target angular acceleration of the whole time history;
一种用于成像卫星主动推扫的四段式轨迹规划方法,规划的运动轨迹按时间顺序分为消初速段、点对点机动段、静止段和角速度预置段,其中点对点机动段又分为加速子段、匀速子段、减速子段三部分,消初速段、角速度预置段、加速子段和减速子段规划的角加速度为正弦函数;然后确定各段的时间点和整个时间历程的目标姿态四元数、目标角速度及目标角加速度。
