Abstract
A differential GNSS ground station is disclosed which generates and broadcasts highly veracious GNSS satellite differential correction data suitable for use in the landing of aircraft. In this context, "veracious` includes the qualities of both accuracy and integrity wherein the broadcast differential correction data is corrupted by a lower level of errors than is customary for the current state of the art and the broadcast differential correction data includes reliable estimates of the noise errors and bias errors corrupting the differential corrections for each GNSS satellite signal. The ground station comprises at least two independent GNSS satellite signal receivers, a processing apparatus for collecting and processing information from the at least two independent GNSS receivers, and a transmitter for broadcasting the composite DGNSS correction signals over a distance.
