Global Navigation Satellite Systems Engineering, Policy, and Design
The development of the Galileo Second Generation (G2) satellites has achieved a significant milestone as independent Satellite Critical Design Review (CDR) boards have confirmed that the satellite designs meet all mission and performance requirements. This accomplishment marks another step forward in the schedule to develop the first 12 satellites of the G2 fleet.

Iridium Communications Inc. has announced the expanded commercial availability of its Satellite Time and Location (STL) service to parts of Europe and the Asia Pacific region. This expansion is driven by increasing demand and aims to provide an alternative positioning, navigation, and timing (PNT) solution to protect critical infrastructure against GPS and Galileo spoofing and jamming.

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.

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.”
