ENVELOPE at ITS EU Congress 2025: Exploring Multi-Connectivity and Non-Terrestrial Networks

The ENVELOPE Project was presented at the ITS European Congress 2025, held in Seville, Spain, during SIS 51,“Space-based Technologies for PNT in Road Mobility”, on 20 May 2025.

Dr. Vasilis Sourlas, from the Institute of Communication and Computer Systems (ICCS), presented ENVELOPE’s work on multi-connectivity and multipath communication, a core component of the project’s effort to enhance reliable, real-time communication for connected and automated mobility (CAM) systems. His presentation focused on how this approach strengthens network performance and service continuity—particularly in complex or dynamic environments.

In addition to showcasing ENVELOPE’s terrestrial communication solutions, Dr. Sourlas engaged in discussions around extending this architecture through the integration of Non-Terrestrial Networks (NTN), including satellite communications. This aligns closely with the session’s broader theme of exploring how space-based technologies—such as GNSS and Satcom—can contribute to safer and more resilient mobility systems.

The session brought together experts from ESA, GMV, Valerann, and ERTICO to address both the technical opportunities and persistent challenges related to Positioning, Navigation, and Timing (PNT). Key topics included GNSS limitations in urban environments, sensor fusion for enhanced positioning accuracy, cybersecurity concerns, and the regulatory path for autonomous mobility.

ENVELOPE’s participation in this session underscored its commitment to innovation in network architectures and its forward-looking perspective on the role of satellite technologies in future mobility ecosystems.
