CLEPSYDRA - Certified gaLileo timE Provision for SYnchronisation of Disciplined Reference scAle

The aim of the CLEPSYDRA Consortium is to team up a group of GNSS and Timing experts and relevant European industries with the objective of bringing to the commercial market the competencies, knowledge and heritage achieved in several years of developments related to Galileo based high-grade timing solutions. The proposed Galileo dual-frequency timing receiver baseline will target a TRL 7/8 platform with a full compliance to the functional and performance targets currently defined in the applicable EN Standard, ensuring a robust and cost efficient design for a competitive commercial product to be deployed in the Energy, Telecommunications, Finance, Transportation domains and Governmental services.

Challenge & technical solution

System operators relying on GNSS-based devices for their timing needs are requiring equipment which are not only stable and accurate, obviously desired key performance in nominal condition, but also capable of detecting hazards and reacting accordingly. Thus to ensure integrity and continuity of service, a robust Timing & Synchronization (T&S) solution will be delivered by the CLEPSYDRA platform, relying on a Multi-frequency GNSS-disciplined time reference, assisted by time solution integrity monitoring (T-RAIM) and protected by Galileo OSNMA and advanced anti-jamming and AI-based anti-spoofing technologies.
