The invention discloses a space deployable two-dimensional tracking turntable system which is used for solving the technical problems that an existing two-dimensional tracking turntable is large in weight, poor in adaptability to a severe mechanical environment of a launching active section and the like. The rotary table system comprises a platform cabin, a load and a rotary table unit, the rotary table unit comprises a base and a supporting assembly, the supporting assembly comprises a supporting seat, a supporting arm and a limiting unit, the supporting arm is movably connected with the end of the supporting seat to form an L-shaped supporting frame body, and in the satellite launching stage, the L-shaped supporting frame body is in a folded state, and after a satellite enters an orbit, the L-shaped supporting frame body is folded. The L-shaped supporting frame body is in an unfolded state, so that the size and the gravity center height of the rotary table unit are reduced, and the mechanical environment adaptability of the space two-dimensional tracking rotary table to a launching active section is improved.

    本发明公开了一种空间可展开二维跟踪转台系统,用于解决现有的二维跟踪转台体重和重量较大,以及对发射主动段恶劣力学环境的适应性较差等技术问题。该转台系统包括平台舱、负载及转台单元,其中转台单元包括底座和支撑组件,支撑组件包括支撑座、支撑臂及限位单元,支撑臂与支撑座的端部活动连接,形成L型支撑架体,在卫星发射阶段,L型支撑架体处于折叠状态,卫星入轨后,L型支撑架体处于展开状态,以此降低了转台单元的体积及重心高度,并提高了空间二维跟踪转台对发射主动段的力学环境适应性。
