摘要
利用改进等效中心投影模型,对欧洲空间局资源卫星(ERS)轨道参数予以精改正。为克服各参数之间强相关性的影响,引入了偏最小二乘回归(PLS)方法,取得了较好结果。
Precise orbit parameters have an important effection in the geometrical using of radar satellite. Based on Konecny model, this paper discussed the correction of ERS satellite orbit parameters. During this course, in order to cope the disadvantage effection brought by the serious correlativity of parameters, the authors proposed to bring a new mathematical models： partial least squares （PLS）, and finally got a good result.
