Orolia, a Safran Electronics and Defense company, announced its Skydel GNSS simulation engine will support Galileo Open Service Navigation Message Authentication (OSNMA) simulation in the form of two-phased and separate solutions. These solutions will be available to users who have purchased simulation access to the Galileo constellation, which will be available in the next few months.
OSNMA is an emerging authentication service that allows GNSS receivers to verify the authenticity of received data to protect against potential jamming or spoofing attacks that can result in service disruptions, denial incidents and more.
The first solution is well-suited for most receiver integrators that want to test the OSNMA capability of a GNSS receiver with the official test vectors from the European Union Agency for the Space Programme (EUSPA). This solution will support the available official test vectors sample data, which supports the verification of OSNMA functionality implementation.
The second option will provide full flexibility in the configuration of the scenario as well as the OSNMA authentication parameters. It will be suitable for advanced users that test receivers in a wide range of edge and corner cases.
Available later in 2023, this phase will include the following elements in Skydel: authentication of the Galileo E1 OS navigation message, a new Skydel engine supporting OSNMA SIS ICD 1.0, support for the timed efficient stream loss-tolerant authentication protocol, and useful crypto material for running user-programmable simulation test scenarios.
This feature will be ready for future software updates in accordance with the next phases recommended by EUPSA.
