A: Receiver Autonomous Integrity Monitoring (RAIM) and Advanced RAIM (ARAIM; known more generally as Solution Separation RAIM, or SS-RAIM) were originally designed to detect, alert and (where possible) exclude faulty measurements caused by Signal-in-Space (SIS) failures.

The US Army released a Request for White Papers (RfWP) to develop new CMFF prototypes. CMFF—C5ISR Modular Open Suite of Standards (CMOSS) Mounted Form Factor—is the Army’s effort to easily and rapidly equip ground vehicles and aviation platforms with capabilities like positioning, navigation, and timing (PNT) and electronic warfare (EW), through capability cards plugged into a common chassis.

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.

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.

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).

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.

GPR Ground Positioning Radar, a producer of ground-penetrating radar technology for autonomous vehicle localization, has announced a strategic collaboration with Rheinmetall Provectus, a global provider of autonomous navigation solutions. This partnership aims to integrate GPR’s WaveSense localization system into Rheinmetall Provectus’ autonomous platforms, enhancing positioning and navigation capabilities in GNSS-denied environments.

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.
