Inside GNSS

Q-CTRL, an Australian quantum infrastructure software company, has reported a field demonstration of GPS-free maritime navigation using a quantum gravimeter, according to a company announcement and an accompanying technical manuscript posted to arXiv.

Poland’s National Institute of Telecommunications reported a sharp escalation in deliberate GNSS interference around the Tri-City area — Gdańsk, Gdynia and Sopot — with data from its Gdańsk monitoring station showing disruption on nearly two-thirds of days so far this month.

The U.S. Army’s Project Manager Positioning, Navigation, and Timing (PM PNT) has awarded a delivery order worth more than $3 million for Dismounted Assured PNT System (DAPS) Mounted Engineering Change Proposal (DME) B-kits, the Army Contracting Command at Aberdeen Proving Ground announced August 25. The order supports first unit equipped to TRX Systems. The DME systems covered by the order will be integrated into medium and heavy tactical vehicles next year, with fielding led by PM PNT.

Resilient positioning data was acquired, tracked and generated on a NovAtel receiver while GNSS signals were jammed, advancing TrustPoint’s C-band service toward commercial availability. TrustPoint announced Aug. 25 that it has demonstrated its C-band navigation signals operating through GNSS interference on an enhanced receiver built by NovAtel, part of Hexagon, under a contract with Naval Air Systems Command.

The Space CSAC-SA65 extends radiation tolerance to 30 kRad and cuts power draw below 120 mW, letting CubeSat-class missions carry atomic-clock timing without relying on GNSS. Microchip Technology on Aug. 13 introduced the Space CSAC-SA65, a radiation-tolerant chip-scale atomic clock designed to bring atomic-clock timing accuracy to small, power-constrained satellite missions.

The configurable stack pairs Javad’s multi-constellation receivers with a choice of commercial or defense-grade IMUs, letting integrators keep producing position, velocity and attitude data when GNSS is degraded. Javad GNSS on Aug. 12 introduced a new GNSS+INS product line built to keep navigation systems operating when GPS signals are jammed, spoofed or denied.

The new Pasternack multi-constellation antenna line targets UAV operators facing increasingly congested RF environments, and will be shown for the first time at the Las Vegas show Sept. 1-3. Infinite Electronics, a global platform of connectivity manufacturing companies, will debut a new lineup of Pasternack multi-constellation GNSS antennas with anti-jamming technology at Commercial UAV Expo 2026, taking place Sept. 1-3 in Las Vegas.

The carrier-grade timing receiver drops into a standard RCB form factor, letting equipment makers add nanosecond-level, jam- and spoof-resistant synchronization without custom RF circuit design. Furuno Electric announced July 28 that it plans to release the RCB-100 GNSS timing receiver in November 2026, packaging carrier-grade time synchronization performance into a standard RCB form factor designed for simpler integration into low-volume equipment.

An ESA NAVISP project has examined how positioning, navigation and timing (PNT) technologies will need to evolve to support increasingly automated road vehicles and other advanced driver assistance systems (ADAS). The project, ‘ADAS technology and PNT’, was led by Acitoflux GmbH and examined the relationship between PNT capabilities and emerging automated-driving applications across the European and Canadian technology landscape.

A look at how detection works and common misperceptions. Public GPS interference maps have become an essential awareness tool for tracking GNSS disruptions worldwide. Services like GPSJAM and GPSwise display interference data derived from aircraft broadcasts, helping aviation professionals and infrastructure operators understand where interference events occur.
