Most Air Navigation Service Providers (ANSPs) use Global Navigation Satellite Systems (GNSS), and often the United States (U.S.) Navstar Global Positioning System (GPS) in particular, to provide timing references to their critical communication, navigation, and surveillance (CNS) and Air Traffic Management (ATM) infrastructures. Legacy CNS/ATM systems may not have the robust alternative timing reference systems required to support continuity of operation in the event of GNSS signal disruption. This study identified potential timing vulnerabilities of systems dependent on GNSS derived timing and risk mitigation approaches to overcome these vulnerabilities.As legacy systems are replaced by future digital systems, CNS/ATM systems will be increasingly time dependent. We present in this paper an overview and analysis of potential GNSS timing risk mitigation options to its vulnerabilities (loss of signal, spoofing, interference, and jamming). Finally, we present a comparison of the risk mitigation options against a set of key parameters (signal disruption, jamming, spoofing, accuracy, ease of deployment and cost).
