Global Navigation Satellite (GNS) signal correction system (2) for estimating and transmitting GNSS signal corrections (A) to a mobile station (30). A method is implemented for providing correction data in a Global Navigation Satellite System (GNSS) based Precise Relative Positioning (PRP) system. The correction data is determined using one or more reference stations, and transmitted to a mobile station with a primary update frequency. The correction data comprises one or more subgroups of correction data (B, I, T), and the one or more subgroups of correction data (B, I, T) are transmitted with a mutually different secondary update frequency (f 1 , f 2 , f 3 ). Also a mobile station (30) is described using the present invention embodiments. |
