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.

It has been widely demonstrated that GNSS-based localization technologies are vulnerable to signal jamming and spoofing/replay attacks, where a receiver can be either denied positioning or deceived to compute a forged PVT solution. Today, it is possible to spoof a GNSS receiver to any arbitrary location and time in the world with many incidents being reported in the wild.

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.

The NOAA Space Weather Prediction Center in Boulder, CO has updated its Geomagnetic Storm Warning for the weekend of May 10 – May 12, 2024. “Significant geomagnetic storming to persist this weekend”, the warning states. “There have been reports of power grid irregularities and degradation to high-frequency communications and GPS”. Aurora effects in the sky were observed as far south as Alabama and Florida.
