| Abstract: | 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. |
