PRESENTIS, or Public Regulated Service Network Time Solution, is designed for governmentally authorised user communities. GMV said the project targets demanding timing and synchronisation needs in critical infrastructures and operational environments.
Secure and resilient timing capabilities are becoming increasingly important where continuity and protection against interference are essential. The project focuses on environments where PRS features such as service continuity, access control and resilience against jamming and spoofing provide advantages over open GNSS services.
PRESENTIS is built around two complementary use cases developed in parallel. These are PRS-based network time synchronisation for civilian applications and PRS-based sensor and data integration combining position and time.
GMV said addressing both use cases at the same time strengthens the technical outcomes. The company said it also broadens the range of potential applications for secure PRS-based timing.
The main objective of PRESENTIS is to merge and exploit the robustness of PRS for the most demanding timing and synchronisation scenarios. GMV and its industrial consortium bring experience in high-capacity timing solutions, including previous work for ESA, large scientific infrastructures and international timing laboratories.
A key element of the project is GMV’s fully operational PRS receiver, developed jointly with CIPHERBIT. GMV said using the receiver as a trusted time source will enhance its WANTime product.
WANTime is GMV’s high-capacity network timing and synchronisation platform. The company said the integration of certified PRS receiver technology will provide PRS-based protection, maximum availability and continuity for critical timing applications.
In parallel, GMV will evolve its PRS server-based navigation solution to assess whether it can be used as a time source for WANTime. This approach centralises key management on a secure server.
GMV said the server-based model enables PRS-based timing for devices without local encryption keys. The company said this can expand the range of deployable use cases.
The project is based on high-technology-readiness-level systems. It combines proven GMV products with Galileo PRS capabilities to deliver a robust and scalable solution.
PRESENTIS also includes engagement with public and private stakeholders. GMV said these activities are intended to raise awareness and demonstrate how secure PRS-based timing can address real operational challenges.
