Precise LEO orbit determination using regional PPP-B2b augmentation services
Abstract The PPP-B2b service broadcasted by BDS-3 GEO satellites can provide centimeter to decimeter-level positioning accuracy in China and surrounding area. As a free satellite based-augmentation system, BDS PPP-B2b service also potentially benefits the low earth orbit (LEO) space users to improve the orbit determination accuracy.
