GNSS degradation events can have significant implications for aviation safety and operations. Effective preparedness, timely response and close coordination across the ATM/ANS community are therefore essential to maintaining safe and resilient operations.
EUROCONTROL has published the first edition of its Guidelines on operational response to GNSS degradations (EUROCONTROL-GUID-203), providing harmonised, practical guidance to ATM/ANS providers, States and other relevant stakeholders on how to prepare for, manage and recover from GNSS degradation events.
The Guidelines establish a common operational approach covering all key stages of response, from preparedness and detection through to coordination, response and recovery. They also provide guidance on relevant aeronautical information services (AIS) products, air traffic services (ATS) procedures, air traffic flow and capacity management (ATFCM) measures and coordination arrangements.
