Abstract
Some embodiments of the invention pertain to methods carried out by a navigation satellite system (NSS) receiver for estimating parameters useful to determine a position. The receiver observes signals from satellites. Delta carrier phase observables are computed by subtracting observables of different epochs. An estimator uses state variables and computes their values based on the computed delta carrier phase observables. A synthetic carrier phase observable for an anchor epoch is generated, for each carrier phase observable of a terminus epoch for which one of the following applies: (i) a change in phase ambiguity occurred with respect to the corresponding carrier phase observable of the anchor epoch, and (ii) no corresponding carrier phase observable was tracked at the anchor epoch. Generated synthetic carrier phase observables are used to compute delta carrier phase observables between the anchor epoch and an epoch subsequent to the terminus epoch. Systems and vehicles are also disclosed.
