OSNMA: Necessary but not sufficient for GNSS security
By Ali Pirsiavash, GNSS resilience researcher, Ali Broumandan, resilient GNSS lead and Sandy Kennedy, VP innovation at Hexagon’s Autonomy & Positioning division
This article published in the Sept/Oct 2024 issue of Inside GNSS+ investigates the performance of the Galileo E1-B Open Service Navigation Message Authentication (OSNMA) in various scenarios, elucidating its logic and workflow and revealing its functionality and intended purpose.
Test results are presented to assess the availability and reliability of the authentication process across static, kinematic and interference scenarios, including spoofing during Jammertest 2023.
With service availability dipping as low as 80% in degraded environments, and limitations in detecting non-navigation message-based spoofing attacks, it is shown that OSNMA still offers a rigid complementary layer of protection to be accompanied by other security features and monitoring techniques for full protection.
