一种卫星姿轨控分层融合数字孪生建模方法及系统

本发明公开了一种卫星姿轨控分层融合数字孪生建模方法及系统，涉及航天控制相关领域，其中方法包括：构建三级分层解耦的卫星姿轨控融合孪生基础模型；基于当前在轨遥测数据置信度评判指标，对卫星姿轨控融合孪生基础模型的三层输出进行自适应动态权重分配，得到融合仿真输出值；利用融合仿真输出值与卫星实际遥测值之间的残差，进行闭环在轨自主迭代演化，得到卫星姿轨控融合孪生更新模型；将卫星姿轨控融合孪生更新模型进行星地两级轻量化分级部署。本申请解决现有姿轨控系统建模方法存在的模型预测精度随在轨时间延长而逐步退化、难以在全寿命周期内持续保持高精度状态复现能力的技术问题。
