chapter5attitude
说明： 卫星姿态是指卫星星体在轨道上运行所处的空间指向状态。将直角坐标系的原点置于星体上，指向地面的Z轴反映偏航方向，Y轴反映俯仰方向，X轴反映滚动方向。星体在高空中沿局部地球铅垂方向和轨道矢量方向运行，不时地产生对三轴的偏移。姿态控制是通过姿态控制分系统（ACS）来实现，使用地平扫描仪可感应俯仰和滚动轴的姿态误差，使用速度陀螺仪和罗盘可感应偏航轴的姿态误差。(Satellite attitude refers to the spatial orientation of a satellite in orbit. The origin of the Cartesian coordinate system is placed on the star, the Z axis pointing to the ground reflects the yaw direction, the Y axis reflects the pitching direction, and the X axis reflects the rolling direction. The stars move along the direction of the earth's vertical direction and the orbit vector in the high altitude, resulting in the deviation of the three axis from time to time. Attitude control is realized by attitude control subsystem (ACS). The attitude error of pitch and rolling axis can be induced by using horizon scanner, and the attitude error of yaw axis can be induced by using speed gyroscope and compass.)

对地面固定目标设计了一种仅依赖测距传感器的制导律，不再需要传统的视线角信号以及目标和无人机自身的定位信息，再将该制导律推广到对地面匀速和变速移动目标的跟踪制导。相比于现有制导律，本课题提出的制导律结构更为简洁，仅有一个设计参数，并且制导策略更为合理。仿真结果表明所提出的制导律能够实现无人机对地面固定目标的稳定跟踪。(A guidance law that only depends on the ranging sensor is designed for the ground fixed target. The traditional line-of-sight signal and the target and the positioning information of the UAV are no longer needed. The guidance law is extended to the uniform and variable speed moving target Tracking guidance. Compared with the existing guidance law, the guidance law structure proposed by this subject is more concise, with only one design parameter, and the guidance strategy is more reasonable. The simulation results show that the proposed guidance law can achieve stable tracking of UAV fixed targets on the ground.)
