摘要： A method for determining at least one real-valued parameter, in particular an absolute or relative position of a receiver is proposed. The method uses a satellite navigation system comprising a plurality of satellites, which emit navigation signals on carrier signals. The method comprises the steps: - phase measurements on the carriers of the navigation signals are performed (12), - a real-valued float solution for at least one real-valued parameter and for phase ambiguities of the phase measurements and a corresponding covariance matrix are determined, - a sequential resolution of the phase ambiguities is performed, wherein a particular ambiguity to be resolved is mapped on a fixed ambiguity in dependency of the previously fixed ambiguities, wherein the mapping of a particular ambiguity to be resolved to the fixed ambiguity is performed by setting the fixed ambiguity equal to a weighted sum of integer candidates for the particular ambiguity, and - the float solution of the at least one real-valued parameter is adjusted to the fixed ambiguities
