Abstract

The invention relates to a method (100) carried out by a navigation satellite system (NSS) receiver or a processing entity receiving data therefrom, for estimating parameters useful to determine a position. The NSS receiver observes NSS signals from NSS satellites over multiple epochs. A first filter (55), called "timely estimator", and second filter (57), called "precise estimator" and delayed with respect to the timely estimator (55), are operated (s120). The estimators use state variables, and make use of NSS signals observed by the NSS receiver or information derived therefrom. The precise estimator (57) further computes its state variable values based on observations that are not derived from NSS signals observed by the NSS receiver. The values of some of the state variables computed by the timely estimator are recurrently replaced (s140) by values from the precise estimator. A corresponding system is also disclosed.
