Optimized architecture of a secondary ground station for generating a secondary SBAS signal in an SBAS system and method of generating a secondary SBAS signal A secondary NLES station comprises a generator (122) of a secondary SBAS signal in a secondary band including no equipment liable to impact on the generation of existing SoL level SBAS signals by an NLES-G2 first station. 10 The secondary NLES station comprises a receiver subsystem (106; 120, 122, 124), configured to receive on a downlink in the secondary SBAS band the secondary SBAS signal from the transmitter subsystem (106) retransmitted by an associated SBAS satellite (10). The receiver subsystem (106) is configured to verify the 15 synchronization and the consistency of the code relative to the carrier of the secondary SBAS signal received via a loop for correction of the phase of the carrier and of the phase of the code of the secondary SBAS signal of the signal transmitted by the transmitter subsystem (104). 20 Figure 2 C'j C C'j co coo C\-I (.0 000w (.0 wC:) o U- 00 0 c'o c'J Ir +
