The Secret to Better Airplane Navigation Could Be Inside the Earth’s Crust

What's up: Nvidia said it can sell its H20 artificial-intelligence chip in China; the Defense Department announces plans to award AI contracts; data centers may be interfering with local water supplies.

Good morning. Satellite-based global positioning systems have been the primary method of aerospace navigation for decades. But with GPS jamming and spoofing on the rise in certain regions, the industry is looking at alternatives.

WSJ's Isabelle Bousquette looks at an effort by Airbus’s Silicon Valley-based innovation center, Acubed, and artificial intelligence and quantum-focused Google spinout SandboxAQ to test the capabilities of one alternative: Quantum sensing.
Acubed recently took MagNav, SandboxAQ's toaster-sized quantum-sensing device, on a large-scale trial, flying with it for more than 150 hours across the continental U.S.
MagNav uses quantum physics to measure the unique magnetic signatures at various points in the Earth’s crust. An AI algorithm matches those signatures to an exact location.
The results showed promise, and as one expert tells the WSJ, the technology's usefulness extends far beyond aerospace. Read the story.

Nvidia said it has received assurances from the Trump administration that it can sell its H20 AI chip in China, days after Chief Executive Jensen Huang met President Trump. The administration in April restricted sales of the chip, which was designed for Chinese customers.
|
|
|
|
The turnaround is being viewed in Beijing as a gesture of good faith in trade talks, people close to official thinking tell the WSJ. Access to chips and advanced technology has been a main priority for Chinese negotiators.

Meta Platforms CEO Mark Zuckerberg said the company is developing a number of “supercluster” data centers, the first of which, Prometheus, will come online next year, Bloomberg reports.
|
|
|
A data center could be contributing to a water crisis in Newton County, Ga., New York Times reports, with reports of damaged wells, dry taps and soaring costs for municipal water. One local authority tells the NYT that a nearby Meta data center uses about 10% of the county’s total water use daily.

Permits will now be required for all high-performance AI chips entering or leaving Malaysia that originate from the U.S., a move aimed at closing regulatory gaps and preventing potential illegal trade, it said in a statement.

European Union officials will hold talks with representatives from Elon Musk’s X after the company’s Grok chatbot last week churned out antisemitic and racist posts, Bloomberg reports. Under the bloc’s Digital Services Act, digital platforms that fail to meet its content moderation requirements can be subject to fines up to 6% of their annual global revenue.

The Department of Defense said it will award up to $200 million in AI contracts to OpenAI, Google, Anthropic and xAI, CNBC reports. “The adoption of AI is transforming the Department’s ability to support our warfighters and maintain strategic advantage over our adversaries,” Doug Matty, the Pentagon's chief digital and AI officer, said in a release.

Elon Musk said Tesla shareholders would vote on investing in xAI, the latest move by the billionaire entrepreneur to tap his own companies to help fund his artificial-intelligence startup. Musk’s comments follow a Wall Street Journal report on Saturday that said SpaceX, his rocket company, had committed $2 billion toward a recent fundraising round for xAI.

After Google’s $4.2 billion deal to license technology from Windsurf, taking some of the AI coding startup’s top executives in the process, Cognition is stepping in to acquire its rival, the NYT reports.

Sun Valley Fashion: The 'Humble' Baseball Cap

Fashion among members of the tech and media elite who gathered last week at Allen & Company's annual confab in Sun Valley, Idaho, included the usual quarter-zip sweaters, but also an array of baseball caps, WSJ's Sam Schube reports.
|
|
|
|
|
But based on photos from the scene this year, the breadth of ball caps—new and vintage, logoed and blank—was striking. A hat is the ideal vehicle for precisely dosed self-expression, particularly if it’s logoed. It doesn’t scream status like a branded T-shirt, nor does it (usually) cost more than a nice lunch. It’s a way for the 1% to act like everyone else, if only from the forehead up, and without risking a style faux pas.
