ESA Addresses Radio-Navigation Commemoration

On 30 July 2024, European navigators commemorated the 90th anniversary of Guglielmo Marconi’s first demonstration of microwave-guided navigation. In the Bay of Silence, off Sestri Levante, Italy, the historic vessel Leudo performed a blind navigation maneuver, crossing the space delimited by two buoys, guided by radio impulses transmitted from the shore. The operation was, in effect, a reenactment of radio pioneer Marconi’s demonstration of 30 July 1934.

Ariane 6 Launches: Impacts for Galileo G2

Ariane 6’s inaugural rocket launch took place from Europe’s Spaceport in French Guiana at 16:00 local time on 9 July. It has taken over from Ariane 5, featuring a modular design that can launch missions from low-Earth orbit and into deep space. Galileo Second Generation (G2) satellites are projected to join the constellation in 2026 with the Ariane 6 launcher. G2 satellites will use electric propulsion and host a more powerful navigation antenna, better atomic clocks and fully digital payloads.

EASA Issues Updated Advisory on GNSS Outages and Navigation Disruptions

The European Union Aviation Safety Agency (EASA) has released a revised Safety Information Bulletin (SIB) addressing the growing issue of Global Navigation Satellite System (GNSS) outages and disruptions. This updated advisory, SIB No. 2022-02R3, highlights the increasing sophistication and impact of GNSS jamming and spoofing, which have become significant concerns for aviation safety.

Consortium Led by KrattWorks Secures €6 Million for Project BadB to Develop GNSS-Free Navigation

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).

Improved Height Determination with GNSS CORS and InSAR Technologies

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.

New NAVISP INSPIRe Project Targets Integrity

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.
