Global Navigation Satellite Systems Engineering, Policy, and Design
In the maritime sector, work is ongoing towards the identification and development of alternative PNT (positioning, navigation and timing) solutions, that is, solutions that are not wholly dependent on GNSS-based technologies.

The Grimaldi Satellite Autonomous Berthing (GSAB) project, funded by the European Space Agency’s NAVISP program, has developed a system enabling automatic, high-precision port berthing operations in large (200m) carrier ships. The system provides ships’ captains and crew with an overview of ship conditions in real time in port settings, including detailed information on maneuvering operations to be performed.

The advantage of incorporating 5G within a global positioning solution lies in its extensive coverage and accessibility, especially in urban areas, where GNSS signal quality can be significantly compromised.

Researchers at the Technical University of Denmark (DTU) have developed a method to monitor daily ice loss in Greenland using data from 61 GPS stations installed on the bedrock around the island. This approach allows for precise tracking of ice melt, providing day-by-day data that enhances understanding of sudden changes in ice mass, especially during the summer.

Galileo satellites GM25 and FM27 were successfully launched into orbit from Kennedy Space Center in Florida on April 27. Thierry Breton, Commissioner of the Internal Market of the European Union, confirmed via X, “2 new Galileo satellites successfully launched last night. Awaiting Ariane6, the 2024 launches are crucial for Galileo’s resilience, robustness and continuity of its civilian & military applications. Galileo deployment will continue in 2025.”

Designed to complement ground-based augmented signals, the new EGNOS Safety of Life Assisted Service for Maritime Users (ESMAS) adds an additional layer of protection against GNSS signal errors, while also increasing signal accuracy and ensuring integrity.

This year’s European Space Policy Conference in Brussels saw familiar faces talking about new and unfamiliar things. While Galileo continues to perform well, delivering an ever-widening range of services, the problem of how to get Galileo satellites into space has forced the Union to take unprecedented, forward-thinking and, for some, uncomfortable steps.

The European Space Agency (ESA) has initiated two innovative navigation missions, Genesis and LEO-PNT, as part of its FutureNAV program, with contracts totaling €233 million awarded to several European entities. This strategic move is aimed at addressing the growing demand for more resilient and precise navigation solutions in Europe.

The European Space Agency (ESA), on behalf of the European Commission, has embarked on a project to enhance the Galileo satellite navigation system with a new ultra-precise atomic clock technology. A €12 million contract was awarded to a consortium led by Leonardo S.p.A of Italy, with the Istituto Nazionale di Ricerca Metrologica (INRiM) acting as the subcontractor.
