本文在LEO卫星简化动力学和SLR检核的原理基础上,利用Bernese5.2软件实现LEO卫星简化动力学定轨和轨道检核。将Bernese5.2软件定轨结果与Bernese5.0软件进行对比,单点定位轨道精度提高了30-40cm,观测值组合定轨在径向、切向和法向上均提高了3cm左右.将定轨结果与GFZ科学轨道进行比较,利用Bernese5.2解算的卫星轨道其拟合精度更高,径向、切向和法向均优于3cm.利用SLR检核LEO卫星轨道,其视向精度优于3cm.
This paper used Bernese5.2software to determinate Reduced-dynamic orbit of LEO satellite and validate orbit with SLR data.Compared with Bernese5.0software,using Bernese5.2to determinate LEO orbit improved 30-40cm of Single-pointposition and 3cm of Reduced-dynamic orbit on radial,normal,tangential direction.Compared with GFZ science orbit,the accuracy of LEO's orbit based on bernese5.2is better with three direction reach to3 cm.When we validate LEO orbit by SLR data,it shows that the accuracy is better than3 cm.
