The invention relates to Navigation-satellite tracking method including at least one step of determining one-way range unambiguous observations for each of a set of satellites in view, wherein standard tracking channels (32, 24) are permanently associated to each of the satellites. It is proposed that the step of determining the one-way range unambiguous observations includes the steps of: Determining one-way range unambiguous and one-way range ambiguous observations with a nearly-hemispherical antenna at a measurement time (tA) for each satellite out of the set of satellites in view simultaneously; Sequentially determining an additional one-way range unambiguous observation and an additional one-way range ambiguous observation with at respectively different further measurement times (tA+k&Dgr;t); and Transforming, satellite per satellite, the additional one-way range unambiguous observations in one-way range unambiguous observations referred to a common future time (tB), wherein this transformation is achieved by adding to each of the one-way range unambiguous observations the temporal evolution of the one-way range ambiguous observations of the respective satellite.
