CEO tells The National that navigation interference and AI vulnerabilities now form a single threat surface for critical systems.

PALO ALTO, Calif., Apr. 28, 2026 /PRNewswire/ — At the World Economic Forum in Davos, Jack Hidary, CEO of SandboxAQ, warned that GPS jamming, GPS spoofing, and AI-enabled cyberattacks are converging into a single operational threat to critical systems. In remarks to The National, Hidary said the threats are no longer separate concerns but overlapping challenges requiring unified resilience.

SandboxAQ addresses both fronts with two technologies: AQNav, which uses the Earth’s magnetic field — the same signal birds and animals navigate by — to deliver resilient positioning, navigation, and timing in GPS-denied environments, and AQtive Guard, which unifies AI security and cryptographic posture management.

GPS interference is shifting from edge case to operational norm:

In June 2025, residents across multiple Middle Eastern countries reported location-service disruptions affecting consumer devices, ships, and aircraft, according to The National.In September 2025, media outlets reported GPS jamming on a flight carrying European Commission President Ursula von der Leyen, attributed to Russian interference.

“Recently, there was a plane flying and because it lost GPS because of jamming, the autopilot would not engage,” Hidary said, citing pilot reports of cascading failures inside aircraft systems. AQNav, tested by the US Air Force and several aviation companies, has drawn interest from Middle Eastern airlines.

Hidary linked GPS disruption to a parallel AI threat: “Large language models are also a vector of cyber attack.” He cited nation-state hackers exploiting generative AI tools, plus the Samsung incident, where engineers entered confidential information into ChatGPT.

The WEF’s 2026 Global Risks Report ranks cyber insecurity #6 among short-term global risks, with adverse outcomes of AI technologies showing the sharpest long-term rise — moving from #30 in the two-year outlook to #5 in the ten-year outlook. The report warns that “technological risks are also anticipated to worsen in severity over the next decade.”

OTTAWA, ON, April 28, 2026 /CNW/ – Tech-Access Canada, the national network of Canada’s Technology Access Centres (TACs), welcomes today’s federal Spring Economic Update, which includes an investment of $165 million over five years to extend support for the College and Community Innovation (CCI) Program.

Delivered through Canada’s tri-council research system and administered by the Natural Sciences and Engineering Research Council of Canada, the CCI Program enables businesses to access applied R&D expertise, specialized facilities, and technical services to advance innovation and bring new technologies to market.

This investment will strengthen Canada’s capacity to support commercialisation and productivity by helping businesses, particularly small and medium-sized enterprises, accelerate the development, validation, and adoption of new products, processes, and technologies.

“Continued support for the CCI Program reinforces a proven model that connects businesses with the expertise and infrastructure they need to innovate and compete,” said Melanie Ross, Research Chair, Green Building Technology Access Centre, Southern Alberta Institute of Technology, and Chair of Tech-Access Canada’s Board of Directors. “Technology Access Centres deliver practical, industry-driven solutions that help companies move ideas forward and translate innovation into real economic outcomes.”

Each year, TACs work with thousands of companies across sectors to advance technologies along the commercialisation pathway from early-stage validation through to deployment and scale-up. By providing objective, non-dilutive support, TACs help companies make informed decisions, avoid costly missteps, and accelerate time-to-market.

“This investment helps ensure that innovation developed in Canada stays in Canada,” said Ken Doyle, Executive Director of Tech-Access Canada. “TACs help companies commercialise here at home reducing risk, accelerating time to market, and driving real outcomes. As Canadian firms scale and export globally, that success returns to the Canadian economy.”

Tech-Access Canada’s network includes more than 70 Technology Access Centres located across the country, providing businesses with access to over 2,100 applied R&D experts, millions of square feet of specialized facilities, and hundreds of millions of dollars in equipment and infrastructure.
