The invention provides a laser communication load ATP structure suitable for a flat satellite, which comprises a telescope assembly, a pitch axis rotating assembly, an azimuth axis rotating assembly and a rear light path assembly, the azimuth axis rotating assembly is transversely and fixedly arranged on the rear light path assembly, the end part of the azimuth axis rotating assembly is fixedly connected with one side of the pitch axis rotating assembly, and the other side of the pitch axis rotating assembly is fixedly connected with the rear light path assembly. The end part of the pitch axis rotating assembly is fixedly connected with one side of the telescope assembly; the azimuth axis of the azimuth axis rotating assembly is orthogonal to the pitch axis of the pitch axis rotating assembly, and the pitch axis is orthogonal to the optical axis of the telescope assembly; light sequentially passes through the telescope assembly, the pitch axis rotating assembly and the azimuth axis rotating assembly and then enters the rear light path assembly. When the mechanism is locked, horizontal installation can be achieved, the telescope and the two-dimensional rotary table can be integrated with the rear light path assembly, the mechanism is smaller and lighter, and installation and adjustment work is simpler and more convenient. The mechanism has higher vibration adaptability when a rocket is launched, so that the capturing, tracking and pointing performance of the mechanism after orbit injection is more reliable.
本发明提供了一种适用于平板卫星的激光通信载荷ATP结构,包括望远镜组件、俯仰轴旋转组件、方位轴旋转组件以及后光路组件,方位轴旋转组件呈横向且固定安装在后光路组件上,其端部与俯仰轴旋转组件的一侧固定连接,俯仰轴旋转组件的端部与望远镜组件的一侧固定连接;方位轴旋转组件的方位轴与俯仰轴旋转组件的俯仰轴,俯仰轴与望远镜组件的光轴之间正交;光线依次经过望远镜组件、俯仰轴旋转组件以及方位轴旋转组件后入射后光路组件。本发明在机构锁紧时能够实现卧式安装,望远镜、二维转台能够与后光路组件集成一体,机构更加小型化、轻量化,装调工作更加简便。机构对于火箭发射时的振动适应性更强,使得入轨后机构的捕获跟瞄性能更加可靠。
