| Abstract: | 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. |
