摘要
WRS-2是为了便于陆地卫星数据的查询和管理而设计的一种全球参考系。本文深入研究了基于WRS-2参考系的2种分景算法WRSID1和WRSID2,比较分析了2种分景算法的异同,最后以Landsat-5为例分别实现2种算法并进行数据验证。通过研究和数据验证,发现WRSID2能显著减少高纬度地区的分景误差。该算法原理适用于美国陆地系列卫星,也能够为其他卫星地面系统的研制提供参考。
WRS-2 is designed for the cataloguing and management of the Landsat satellite data.This paper studies two framing algorithms based on WRS-2,which are WRSID1 and WRSID2.Then,it implements the two algorithms based on Linux and Eclipse IDE for C/C++using Landsat-5 sample data.Experiment result shows that WRSID2 algorithm can minimize the framing error in pole areas.This algorithm is not only applicable for Landsat satellites,but also can provide references for the development of other satellite ground systems.
