The invention relates to a two-stage unfolding and double-shaft tracking satellite-borne antenna gravity unloading system, which is used for realizing ground simulation unfolding and rotation tracking of a satellite-borne antenna comprising two unfolding shafts. Comprising a turnover vehicle, a fixing tool, a constant-tension unloading system, a racemization unloading system and an unloading truss. The satellite-borne antenna ground unfolding rotation tracking with a two-stage unfolding double-shaft rotation tracking function is realized, the unloading difficulty of a multi-shaft antenna is reduced, the unloading effect is improved, the antenna ground unfolding rotation precision is improved, and credible rotation test data is provided for orbit.
本发明是一种两级展开双轴跟踪星载天线重力卸载系统,用于实现包括两个展开轴在内的星载天线地面模拟展开及转动跟踪。包括:翻转车、固定工装、恒张力卸载系统、消旋卸载系统和卸载桁架。本发明使具有两级展开双轴转动跟踪功能的星载天线地面展开转动跟踪得以实现,降低了多轴天线的卸载难度,改善了卸载效果,提高了天线地面展开转动的精度,为在轨提供可信的转动测试数据。
