Global Navigation Satellite Systems Engineering, Policy, and Design
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.

GPS technology developer oneNav has announced the successful results of a test of its technology’s resilience to widespread GPS interference. The tests took place in and around Haifa, Israel, and examined the performance of its L5-direct GPS receiver against the performance of GPS receivers in leading smartphone and smartwatch brands.

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.

Taoglas, a provider of antennas and IoT components, has announced the launch of Inception, a new GNSS L1/L5 ultra-low-profile “patch-in-a-patch” antenna. The HP5354.A offers dual-band stacked patch performance in a single 35 x 35 x 4mm form factor. This design integrates the second antenna within the first, eliminating the need for stacking parts and reducing the antenna height by 50%.

When Jeffrey Sanders founded UHU Technologies a few years after selling his first company, it wasn’t because he needed the work or a new income stream. He wanted to fix the GNSS spoofing and jamming problem impacting the U.S. and allied militaries. He did it primarily for the warfighter, and said this is the work that will become his legacy.

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.
