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 (32,34) 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 (10,12) at a measurement time (t A ) for each satellite out of the set of satellites in view simultaneously;
- Sequentially determining an additional one-way range unambiguous observation with a directional antenna (16,14) and an additional one-way range ambiguous observation with at respectively different further measurement times (t A +k”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 (t B ), 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. |
