用地球磁场和重力场成功挽救风云一号（B）卫星的控制技术

风云一号气象卫星是我国最早成功发射的太阳同步三轴稳定对地遥感卫星，由于早期的技术和器件原因，星上计算机因空间辐照而失控，造成星上贮气耗尽、卫星高速翻滚。本文详细介绍了了在卫星面临失败的情况下，作者利用地球磁场和重力场与卫星的相互作用，采用星上的磁力矩器和可用的一切手段而设计的一整套抢救这颗卫星的技术方法，并简述了经过75天的艰苦努力，使这颗濒临失败的卫星重新建立三轴稳定的对地定向姿态的历程。

TECHNIQUE OF SUCCESSFUL RESCUE OF FY-1B METEOROLOGICAL SATELLITE BY USING THE GEOMAGNETIC FIELD AND THE GRAVITATIONAL FIELD GEOMAGNETIC FIELD AND THE GRAVITATIONAL FIELD

FY-1 meteorological satellite is the first sun-synchronous earth-pointing three-axis stabilized remote sensing satellite launched successfully in China.Because of early technique and components,on-board computer failed to work due to the space radiation,which causes the consumption up of the gas and tumbling of the satellite at high rate.In this paper,technical approaches of rescuing the satellite by using magnetic rods and possible measures through the interaction of the geomagnetic field and gravitational field on the satellite are introduced in detail.The flight history of the satellite to achive earth reacquisition following temporary failure after 75 days’ endeavor is also presented briefly.
