Yaw attitude modeling for BeiDou I06 and BeiDou-3 satellites
TL;DR: In this paper, an alternative yaw attitude model similar to that used for the Galileo Full-Operation-Capacity (FOC) satellites was developed on the basis of the estimated BeiDou I06 yaw angles with an accuracy of approximately 3.4°.
Journal ArticleDOI
Accounting for perturbing forces acting on Galileo using a box-wing model
TL;DR: In this paper, a hybrid box-wing solution with a reduced set of empirical parameters was proposed for precise orbit determination, orbit prediction, and estimation of geodetic parameters, which substantially reduces the variance of satellite laser ranging (SLR) residuals.
