Integrated Configuration Design of Platform and Payload for Remote Sensing Satellite

随着遥感卫星制造技术的不断提高,高精度、高敏捷性、低成本遥感卫星的需求日益强烈。平台与载荷一体化设计是未来高精度、高敏捷性、低成本遥感卫星发展的重要方向之一,平台与载荷一体化构型设计是平台与载荷一体化遥感卫星的关键。目前已有多颗平台与载荷一体化构型的遥感卫星在轨飞行,中国尚处于起步阶段。文章分析了平台与载荷一体化设计的遥感卫星构型;从提高图像定位精度、降低卫星质量、降低建造成本等方面,分析了平台与载荷一体化构型的优势;对载荷设计需具有整星级优化理念、载荷需提供多种接口、平台与载荷间具有强耦合关系等一体化构型的特点进行了总结;给出了一体化构型的建议,如整星形状设计、主承力结构设计、大型部件布局等。

As the modem remote sensing satellite technology developing, the demands for high resolution, high agility and low cost are becoming more and more urgent. The integrated design of remote sensing satellite is an important direction for high resolution, high agility and low cost remote sensing satellite. The integrated configuration design is a crucial factor for satelliteintegrated design. Several remote sensing satellites of integrated configuration have been in orbit abroad, but it is only at the beginning of development at home. The paper analyzes the configuration of remote sensing satellite integration design and gives the advantages of the configuration design as promoting positioning accuracy and decreasing mass and cost. It points out the difficulties and characteristics like systematically considering load design, providing multi-interface on load and strong coupling between platform and payload. Finally, it makes suggestions on constructing the shape, designing the main frame and placing the large equipment.
