Satellite radio-navigation system with remote architecture

摘要

The station (104) has a transmission/reception VHF antenna (140) and a transmission/receiving unit (141) transmitting navigation information to satellite radio-navigation receivers (101-103). A reference path comprises a beam forming directional antenna (144) for receiving radio-navigation signals transmitted by a satellite. A processing unit (145) processes the signals. A calculating unit (146) performs reliability improvement, control integrity and an authentication of the navigation information based on measurements provided by the processing unit. Independent claims are also included for the following: (1) a satellite radio-navigation receiver (2) a satellite radio-navigation system.
