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30~40 cm,观测值组合定轨在径向、切向和法向上均提高了3 cm 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3 cm.利用 SLR 检核 LEO 卫星轨道,其视向精度优于3 cm.%This paper used Bernese5.2 software to determinate Reduced-dynamic orbit of LEO satellite and validate orbit with SLR data.Compared with Bernese5.0 software,using Bernese5.2 to determinate LEO orbit improved 30~40 cm of Single-pointposition and 3cm of Reduced-dynamic orbit on radial,normal,tangential direction.Compared with GFZ science or-bit,the accuracy of LEO’s orbit based on bernese5.2 is better with three direction reach to 3cm.When we validate LEO orbit by SLR data,it shows that the accuracy is better than 3cm.
