OPTIMISED ARCHITECTURE OF A SECONDARY GROUND STATION FOR GENERATING A SECONDARY SBAS SIGNAL IN AN SBAS SYSTEM AND METHOD FOR GENERATING A SECONDARY SBAS SIGNAL

摘要

A secondary NLES station comprises a generator (122) of a secondary SBAS signal in a secondary band being devoid of equipment capable of impacting the generation of existing SoL-level SBAS signals by a first NLES-G2 station. The secondary NLES station includes a receive channel (106; 120,122,124) configured to receive the secondary SBAS signal from the transmit channel (106) downstream in the secondary SBAS band and retransmitted by an SBAS satellite. (10) associate. The receive chain (106) is configured to control the timing and coherence of the code relative to the carrier of the secondary SBAS signal received through a carrier phase correction loop and the signal code phase. Secondary SBAS of the signal transmitted by the transmission channel (104).
