Abstract

Abstract: Geolocation of airborne data is used to determine each pixel’s latitude and longitude，which is the foundation for later data analysis procedure.This paper introduces the method for airborne data geolocation.Firstly，give the description of the problem.Secondly，set up the flight and attitude model for the geolocation.Thirdly，present the algorithm for this method.Finally，this method is proved to be effective and of high accuracy by the given computation results and error analysis.This method is not only fit for the meteorological polar satellite airborne data geolocation，but also for other remote sensing satellite. And thus is of great importance.

Key words: remote sensing satellite, airborne, geolocation

摘要： 航空校飞数据的地理定位方法用来确定数据中每一个像素的地理经纬度，它是整个数据处理过程的基础。介绍了一种用于航空校飞试验数据的地理定位方法。首先给出了问题的描述；其次建立了航迹和姿态模型；然后给出了地理定位方法的算法；最后给出计算结果及误差分析，验证了方法的可行性以及高精度。地理定位方法不仅仅可以用于极轨气象卫星的校飞试验数据处理，同时也适用于其他遥感卫星的校飞试验数据处理，具有非常重要的意义。
