GNSS Disruption is No Longer a Concern. It is Now a Disruptive Reality.
The world relies on the Global Navigation Satellite System (GNSS) to provide position, navigation, and timing (PNT) services for a myriad of uses. These include critical infrastructure, such as power grids and wireless communication services, along with navigation systems for vehicles, ships, and aircraft. In the Middle East, these essential services are all under attack today. The concern of electronic warfare disrupting GNSS is no longer a warning, but a daily reality that is creating an unprecedented impact.
For example, in January 2026, The Washington Post reported that the Iranian government deliberately disrupted Starlink’s internet service to cut off communication between citizens and the outside world, forcing Starlink to scramble to restore connectivity. In June 2025, two ships collided near the Strait of Hormuz. According to the Financial Times, the Liberian tanker “Front Eagle” experienced GNSS spoofing just hours prior to the collision. While the GNSS disruption has not been named the cause of the collision, it is clear the risk to maritime shipping has never been higher. More recent reports estimate that over 1,100 ships in the Gulf region have experienced GNSS disruption.
What does this really mean? Redundancy is essential in most areas of modern technology, and positioning and timing systems are no exception. Alternate and complimentary PNT sources beyond GNSS are no longer something to be considered—they are essential to maintaining critical operations and safety.
APNT offers critical strength through redundancy
The market is quickly flooding with assured positioning, navigation, and timing (APNT) solutions. But, as is often said, “buyer beware” as not all solutions are equal. How do you know which solutions only offer hope, and which provide real protection? You have to do your research. Where to begin?
In January 2026, the UK Royal Institute on Navigation (RIN) published the “Impacts of GNSS Interference on Maritime Safety,” highlighting the urgent crisis of jamming and spoofing to vessel safety. This report calls for immediate action to reduce reliance on vulnerable GNSS and offers key recommendations to buyers when evaluating and selecting alternate PNT technology systems, including:
- Strengthening GNSS robustness
- Adding authenticated and secure PNT sources
- Reducing reliance on open GNSS
- Validating equipment performance under interference
- Adopting alternative PNT technologies
While the report is focused on the maritime industry, these recommendations are applicable to all industries. APNT solutions by NAL Technologies (Naltec) meet each of these and more.
Naltec’s APNT products offer reliable PNT when GNSS cannot. APNT by Naltec solutions contain advanced technology that makes them much more resilient to disruption with lower power consumption compared to other products on the market. Naltec’s market-leading PntGuard™ solution and APNT modules feature jamming and spoofing detection, multi-constellation GNSS receivers, and a host of other proprietary features. They also leverage the Iridium low-Earth orbit (LEO) signal, which is approximately 1,000 times stronger than GNSS.
“Whatever solution you choose, make sure it has been tested, vetted, and verified. Ask to see results,” said Rob Gillette, Director of APNT Solutions for Naltec. “Pick the right solution and don’t fall for the hype.”
