METHOD FOR PROVIDING A CORRECTION INFORMATION, PLURALITY OF REFERENCE STATIONS AND A CENTRAL COMPUTATION UNIT, GNS SYSTEM AND SOFTWARE PRODUCT AND/OR NETWORK FOR PROVIDING A CORRECTION INFORMATION IN A GNS SYSTEM

摘要

A method for providing authenticated correction information (20), in particular orbit, clock and bias/offset correction information, to a mobile receiver (5) in a GNS system, comprising:- receiving raw data from satellites (2) at a plurality of reference stations (15);- forwarding the raw data received at the reference stations (15) to a central computation unit (30), in particular to a single central computation unit, using a data stream (18), in particular a common data stream;- determining the correction information (20) at the computation unit (30) based on the raw data received from the different reference stations (15) and- transmitting the correction information (20) via at least one satellite (2) to the receiver (15) for reliably determining a position of the mobile receiver (5).
