摘　　要：圆锥扫描式红外地球敏感器常用于测算地心矢量,而地球扁率影响地心矢量精度。研究了基于地球扁率的地心矢量的修正算法,并将该方法应用于双圆锥红外地球敏感器,给出了考虑扁率的地心矢量计算方法。仿真结果表明,该方法能有效地提高地心矢量的计算精度。The scanning infrared sensor is used to measure the geocentric vector. Accuracy of the measurements of the geocentric vector is affected by the earth oblateness. This paper discusses the correction algorithms of measurements of the scanning infrared sensor based on earth oblateness and its application in the double-cone scanning infrared earth sensor and then presents a correction algorithm. The simulation shows its validity.
