Abstract

Some embodiments of the invention relate to methods carried out by an NSS receiver and/or a processing entity capable of receiving data therefrom, for estimating parameters derived from NSS signals. An estimator is operated, which uses state variables and computes the values thereof based on delta observables computed for a previous epoch. Previous residuals are obtained from the estimator, each previous residual being associated with a delta observable computed for the previous epoch. The previous residuals are then adjusted using a back-residual coefficient. Delta observables for a current epoch are computed. For each of at least some of the delta observables, the delta observable computed for the current epoch is corrected using the adjusted previous residual associated with the delta observable. The estimator is then operated for the current epoch at least based on the corrected delta observables.
