GPS-Denied Is No Longer a Feature — It's a Baseline Requirement

For years, "works when GPS doesn't" was a nice-to-have — a niche capability for specialized operations. That's changing fast.

Jamming and spoofing are no longer rare or exotic. They surface in headlines around aviation, shipping, and conflict zones with growing regularity, and the tools to cause them keep getting cheaper and more available. Add the plain physics — GPS simply doesn't work indoors, underground, or in dense urban canyons — and the conclusion is hard to avoid: any system that depends on a single positioning source has a single point of failure.

As autonomy spreads into environments where position can't drop, GPS-denied capability is moving from a specialized feature to a baseline requirement. If a robot, a drone, or a critical facility can only locate itself when it can see and trust satellites, it isn't resilient — it's exposed.

The answer isn't to replace GNSS. It's to complement it — with an independent, terrestrial layer that keeps working when the satellite signal is jammed, spoofed, or simply unavailable. And the most practical place to build that layer is the wireless infrastructure already deployed almost everywhere: existing Wi-Fi, read passively, with no new constellation, no correction services, and no new hardware.

Resilience was never about one perfect signal. It's about redundancy — two independent sources that fail in different ways. As Physical AI moves into the real world, a second, independent positioning layer stops being optional. It becomes the baseline.
