1. Station for receiving satellite radio navigation signals, comprising a wideband transceiver for receiving a specific signal transmitted by a transmitter/receiver and for extracting at least one radio navigation signal, called a user radio navigation signal, that said specific signal contains, a first centralized processor for digitally processing said user radio navigation signal that is configured for determining a measurement of pseudo distance that is associated with said signal and a centralized calculator for calculating navigation information (PVT) on the basis of said measurements of pseudo distance, said wideband transceiver being further configured for transmitting said navigation information (PVT) to said transmitter/receiver, the reception station having a first reference channel for receiving radio navigation signals having at least one directional antenna for forming a channel for receiving radio navigation signals transmitted by at least one satellite, a second processor for processing the radio navigation signal received by said directional antenna for forming a channel and a calculation unit that is configured for performing, on the basis of the measurements provided by said second processor, an improvement in reliability, an integrity check and authentication of said navigation information (PVT), the calculation unit having at least one first security module that is configured for implementing, in centralized fashion, the deciphering of the spread codes and of the data from all of the user radio navigation signals.
