Abstract
GNS signal correction system and method for calculating GNSS corrections, and complementary mobile and mobile position determination method based on these GNSS corrections. The methods employ satellite-single-differenced mixed code-and-phase system hardware delays in modelling carrier phase system observables. These system hardware delays are dynamically estimated by the signal correction system using a dynamic system state model. The estimated system hardware delays are transmitted to the mobile, which applies these delays to a dynamic mobile state model, in order to improve the accuracy and/or convergence time of mobile position estimations.
