MGR-DCB: A Precise Model for Multi-Constellation GNSS Receiver Differential Code Bias [PDF]
Journal of Navigation, 2015 In this study, we develop a Multi-constellation Global Navigation Satellite System (GNSS) Receiver Differential Code Bias (MGR-DCB) model. The model estimates the receiver DCBs for the Global Positioning System (GPS), BeiDou and Galileo signals from the ionosphere-corrected geometry-free linear combinations of the code observations. In order to account
