Abstract
A method for determining positions of a mobile system is disclosed. The method involves receiving, by a receiver of the mobile system, a first set of correction data which is broadcasted from a first transmitter, wherein the first set of correction data comprises Differential Global Navigation Satellite System (D-GNSS) correction data, estimating, using a real-time kinematics (RTK) method, a first position of the mobile system using at least a portion of the first set of correction data, estimating one or more unknown parameters of a precise point positioning (PPP) estimation method based at least on the estimated first position of the mobile system and the first set of correction data, and estimating a second position of the mobile system using the estimated one or more parameters and the PPP estimation method, wherein the second position of the mobile system is different from the first position of the mobile system.
