When Justin Deifel sat down with Inside GNSS at XPONENTIAL, it was his first media interview since joining Xona as vice president of government programs. The setting was fitting. Xona is moving Pulsar, its low Earth orbit (LEO) PNT service, toward operational status at a time when government, defence, infrastructure and commercial users are reassessing long-standing dependence on GNSS alone.
Deifel joined Xona in May after a career across the U.S. Space Force, Air Force, national security space and intelligence communities. His recent assignments included chief of staff for PEO Space Sensing, squadron commander and materiel leader for Resilient GPS, program manager and materiel leader for the Military SATCOM and PNT Directorate Futures division, and leadership roles supporting MUOS, the Enhanced Polar System Recapitalization and future GPS capabilities. Earlier, he worked at Edwards Air Force Base on test range capabilities and flight test programs, deployed to Afghanistan in support of air operations, led U.S. government and commercial testing related to terrestrial network interference with GPS, and managed elements of the GPS III space vehicle program.
“Rapid innovation in launch and satellite communications has shown that commercial companies can deliver capability at the speed of relevance,” Deifel said. “Xona is bringing that same approach to rethinking positioning, navigation and timing for the modern era with Pulsar.”

Septentrio, part of Hexagon, has announced the launch of the mosaic-G5 P8 receiver. The multi-frequency module, measuring 23 mm by 16 mm and weighing 2.2 grams, enables accurate and resilient positioning without any performance compromises for mission-critical devices, UAVs, marine vessels, and rail applications.
Built for reliable operation in contested GNSS environments, AIM+ Ultimate technology protects the receiver from powerful and sophisticated GNSS jamming and spoofing attacks. It delivers comprehensive situational awareness, combining timely interference and spoofing indicators with detailed power and frequency data, which can help localise jammers.

ArkEdge Space Inc. has completed a study commissioned by the Japan Aerospace Exploration Agency (JAXA) on “Elemental Technologies and Systems for a Dedicated, GNSS-Independent LEO-PNT Satellite System.”
Positioning, navigation and timing derived from GNSS is increasingly subject to interruption and interference, both through environmental and security challenges. Finding methods to protect PNT information against such interference is of paramount importance for governments and commercial actors alike.

The ArkEdge/JAXA project addressed such challenges by examining and categorizing the necessary elemental technologies — signal design, receiver technology, ground infrastructure, satellite sensors, and the overall system architecture — required to realise a LEO-PNT system capable of providing PNT without reliance on traditional GNSS.

On a January morning in 2026, a GPS jammer powered up near Shiraz, Iran. It was not the first, and it would not be the last. The Strait of Hormuz corridor has become one of the most persistently jammed airspaces on Earth. But this time, two satellites were watching from very different vantage points, and together they would demonstrate something new: that spaceborne sensors can localise a terrestrial GPS jammer to within a few kilometres, using physics alone.
This article presents the first direct comparison of Cyclone Global Navigation Satellite System(CYGNSS) — a NASA GNSS reflectometry constellation — and NASA-ISRO Synthetic Aperture Radar (NISAR) — an L-band synthetic aperture radar for GPS jammer localization. The results challenge assumptions about which modality performs better and reveal that the answer depends on a question most analysts forget to ask.

Trimble is supporting Project Pressure by providing advanced GNSS positioning technology and research funding for the nonprofit organisation’s latest expedition to map the disappearing tropical glaciers of Puncak Jaya in Papua, Indonesia.
Project Pressure has released a centimetre-accurate, 3D model of the receding ice, created using Trimble positioning technology and drone-based photogrammetry. The model establishes a scientific baseline for calculating the rate of glacier recession and projecting the timeline of disappearance.
Puncak Jaya, the highest peak in Oceania and one of the Seven Summits, is expected to be the first of the seven continental peaks to lose its glaciers as global temperatures rise.
Local communities use the data to make informed choices about crop selection and prepare for expected water shortages caused by the loss of vital reservoirs.

TrustPoint has been awarded a $4 million Tactical Funding Increase (TACFI) contract to demonstrate a GPS-independent positioning, navigation, and timing system. The award was issued by SpaceWERX, the innovation arm of the United States Space Force, and jointly funded by the Small Business Innovation Research program and the Commercial Space Office.
TACFI awards are typically valued at around $2 million and usually require a private capital match. In this case, SpaceWERX provided the full $4 million, with no matching investment required from TrustPoint. CEO and founder Patrick Shannon described the award as a demand signal from the government for C-band GNSS from LEO.
Under the contract, TrustPoint will design, deploy, and operate a fully integrated PNT system comprising four satellites and four ground stations, delivering a complete operational architecture including live trilateration across multiple space and ground assets. TrustPoint currently has three single satellites in orbit as early technology demonstrators; the four-satellite constellation funded by the TACFI will demonstrate the full operational capability.

BAE Systems Geospatial eXploitation Products (GXP) and Vantor will be providing advanced intelligence and targeting capabilities for contested electronic warfare environments.
The delivery integrates part of Vantor’s Raptor, a vision-based software suite that enables autonomous systems to navigate, orient and extract accurate ground coordinates without relying on GNSS, with the GXP software ecosystem, ensuring intelligence continuity when sensors are degraded.
In modern conflict zones, the proliferation of inexpensive unmanned aerial systems (UAS) with equally low-quality sensors, in addition to widespread GPS spoofing and jamming, have rendered traditional drone video collection unreliable. Significant metadata drift in tactical video feeds leads to “targeting paralysis”: high-quality imagery is available, but the underlying geographic coordinates are too inaccurate for precision activities.
To solve this, Raptor Sync georegisters the full-motion video feed from the drone’s on-board camera with Vantor’s 3D terrain data in real time, enabling downstream GXP intelligence fusion, multi-domain interoperability across different sensors, and accurate ground coordinate extraction at a demonstrated absolute accuracy of

UK MoD Awards £6 Million eLoran Contract to QinetiQ-Led Team Elaris
The UK Ministry of Defence has awarded a £6 million contract to Team Elaris, a QinetiQ-led consortium, to develop a deployable concept for enhanced Long-Range Navigation (eLoran) as a GPS-independent positioning, navigation, and timing alternative for military operations in contested environments. The two-year effort falls under the Urgent Compass programme.
Team Elaris comprises QinetiQ, UrsaNav, Roke, and GMV — bringing together U.S. and European PNT expertise across deployable and fixed eLoran architectures. Work completed under the programme will inform future demonstration, production, and deployment packages. The contract extends QinetiQ’s existing engagement with the MoD on assured PNT, which also includes the Robust Global Navigation System programme — a separate component of the UK’s broader resilient PNT strategy.
The MoD framed the award around the growing threat of GNSS jamming and spoofing in battlefield environments, noting that a compromised satellite navigation signal can result in misdirected troop movements or incorrectly guided munitions. Urgent Compass is specifically designed to explore eLoran solutions that can be rapidly deployed to contested locations worldwide.
