摘要
本文介绍了icesat卫星激光测高的相关信息、激光测高产品的误差来源及其纠正,并通过对icesat激光测高三期数据交叉点平差初步分析,得出通过交叉点平差可以降低卫星轨道误差对激光测高的影响。
In this paper, we introduce some information of the ICESat satellite laser altimeter, the error source and its correction of the laser altimetry data products, preliminary analysis three operation ICESat data by using crossover adjustment; we derived that the satellite orbit error on the impact of the laser altimeter can be reduced effectively by the crossover adjustment.
