Abstract:
1. A method comprising: using, by an apparatus, received measurements on satellite signals that are valid for a first reference station and data provided by a satellite signal receiver for solving integer ambiguities for a baseline between the satellite signal receiver and the first reference station and for tracking the baseline between the satellite signal receiver and the first reference station; and performing, by the apparatus, a change of reference station by using measurements on satellite signals that are valid for the first reference station and measurements on satellite signals that are valid for a second reference station, which have been received in parallel for a limited time for supporting the change of reference station, and data provided by the satellite signal receiver for solving integer ambiguities for a baseline between the satellite signal receiver and the second reference station under consideration of a baseline between the first reference station and the second reference station, and by using received measurements on satellite signals that are valid for the second reference station, data provided by the satellite signal receiver and the solved integer ambiguities for a baseline between the satellite signal receiver and the second reference station for tracking the baseline between the satellite signal receiver and the second reference station.
