[IGSSTATION-9104] KOUG00GUF : maintenance on 10 MHz input signal

[Operation Regina]

Author : REGINA Team
 
Dear Colleagues,
 
For your information, DORIS maintenance was performed in Kourou, impacting an interface of the Regina KOUG receiver, specifically its 10 MHz input:
- Nov. 2025 13th 20:45 UTC:  The receiver switched to internal 10 MHz signal generation following the shutdown of the DORIS control unit.
- Nov. 2025 14th 18:25 UTC : The receiver returned to external 10 MHz reference (via new TMG DORIS equipment, still controlled by cesium).
 
Best Regards,
