敏捷卫星姿态机动过程分析与可视化判读平台设计

Process Analysis and Visualization Platform Design and Implementation of Attitude Maneuver Mode for Agile Satellite

针对传统的成像姿态及姿态角速度的判读方式不再适用于敏捷卫星复杂姿态机动测试的问题,提出了一种基于实时测试场景的载荷对地成像轨迹计算方法,以Matlab软件为计算平台,实现成像轨迹、地面成像点(简称成像点)移动速度等多项指标数据的实时判读;利用Matlab与STK软件双向通信技术,开发了基于STK软件的实时数据可视化判读平台。整星测试结果表明:该平台实现了敏捷机动复杂过程分析与可视化判读,为开展整星综合测试和在轨任务分析提供了理论参考和实用工具。

The traditional interpretation methods for imaging attitude and attitude angular velocity are no longer suitable for complex attitude maneuver testing of agile satellites.To solve this problem,a real-time load imaging trajectory calculation method based on real-time test scenario is proposed.The real-time interpretation of imaging trajectory and moving speed of point under mirror is realized by using Matlab as the computing platform.A real-time data visualization interpretation platform based on STK is developed by using the bidirectional communication technology between Matlab and STK.The system-level test results show that the platform achieves agile maneuvering complex process analysis and visual interpretation,and provides a theoretical reference and practical tool for the development of integrated satellite test and on-orbit mission analysis.
