Global Navigation Satellite Systems Engineering, Policy, and Design
The European Defence Fund (EDF) and the Ministries of Defence of Estonia and Finland have awarded a €6 million investment to Project BadB, a consortium led by Estonian defence technology company KrattWorks. The project focuses on developing advanced navigation solutions for land and aerial vehicles that do not rely on global navigation satellite systems (GNSS).

Researchers in Hungary have developed a new method for geodetic height determination, exploiting the synergies of multi-constellation GNSS and interferometric synthetic aperture radar (InSAR). The solution, proposed by the Lechner Knowledge Center in Budapest, comprises a modernized reference network of integrated, continuously operating reference stations (CORS) with InSAR corner reflectors.

The European Space Agency’s NAVISP program continues to churn out on-point, PNT-related research at a time of increasing interest in the resilience, or lack thereof, of GNSS-based solutions. Among the latest NAVISP-funded projects to achieve completion is INSPIRe (Integrated Navigation System-of-Systems PNT Integrity for Resilience), which investigated a number of approaches for providing integrity of GNSS-derived PNT for maritime users.

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.
