Autonomous Mission Planning Design and Application of a Fast Responsive Small Satellite

浦江一号卫星是由上海航天技术研究院研制的一颗快速响应型小卫星,于2015年9月成功发射,卫星质量347 kg,运行在高度481 km的太阳同步轨道。为高效、高精度识别定位地面大范围广泛而随机分布的电磁辐射目标,浦江一号卫星提出了基于单星电磁信号监测载荷与光学成像载荷综合应用的在轨自主任务规划方案。在轨应用表明:该设计解决了电磁信号监测与光学成像高效协同难题,实现了星上自主任务规划时间快于0.10 s,引导指向精度优于0.10°,单次任务连续引导目标数量多于10个,为后续多手段遥感卫星的综合应用及在轨自主任务规划设计提供借鉴。

PJ-1 satellite is a fast responsive small satellite developed by Shanghai Academy of Spaceflight Technology. It was successfully launched into the scheduled orbit in September 2015 with a mass of 347 kg,and runs in a sun-synchronous orbit at an altitude of 481 km. In order to identify and locate electromagnetic radiation targets in a wide range and randomly distributed on the ground with high efficiency and precision,an on-orbit autonomous mission planning design is proposed for PJ-1 satellite by the integrated application of electromagnetic signal monitoring load and optical imaging load. The on-orbit application shows that the design solves the problem of efficient cooperation between electromagnetic signal monitoring and optical imaging,and realizes the on-orbit autonomous mission planning time is faster than 0.10 s,the guidance pointing accuracy is better than 0.10 °,and the number of continuous guidance targets for a single mission is more than 10. The design can provide a reference for the subsequent comprehensive application of multi-mean remote sensing satellites and on-orbit autonomous mission planning.
