【摘要】：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.
[Abstract]:On the basis of the principle of LEO satellite simplified dynamics and SLR check, this paper uses Bernese5.2 software to realize LEO satellite simplified dynamic orbit determination and orbit check. Comparing the orbit determination results of Bernese5.2 software with that of Bernese5.0 software, the accuracy of single point positioning orbit is improved by 30 ~ 40 cm, and the observed value combination orbit determination increases about 3cm in radial direction, tangential direction and normal direction. The results of orbit determination are compared with that of GFZ scientific orbit. The satellite orbit calculated by Bernese5.2 has higher fitting accuracy, and the radial, tangential and normal directions are better than 3 cm. Using SLR to check the orbit of LEO satellite, the apparent direction accuracy is better than 3 cm.
