> Locata's system resolves this issue by layering in an independent
> network of transceivers that communicate over ground. A test last
> year in Washington, D.C., by the U.S. Naval Observatory, the division
> responsible for maintaining the GPS master clock, found that Locata's
> web of signals synced up within 200 trillionths of a second, more
> than 50 times faster than GPS. And unlike GPS, the signals are strong
> enough to pass through walls. “We're analogous to a Wi-Fi hotspot,”
> explains Locata CEO and co-founder Nunzio Gambale, who has been
> designing the system for some 20 years.
>
> The system most likely is a decade from the consumer market but has
> proved successful so far in commercial partnerships, including a
> recent deal with the nasa Langley Research Center, where the
> technology assists tests of unmanned aircraft safety systems. Locata
> networks also have helped assess the efficacy of vehicle
> crash-avoidance systems at the Insurance Institute for Highway Safety
> and have been used to monitor U.S. Air Force aircraft locations at
> the White Sands Missile Range in New Mexico, where GPS is currently
> jammed to simulate warfare environments.
>
> Ideally Locata transceivers would be integrated into all cellular
> towers, bringing centimeter-level location accuracy to everyday
> consumers, Gambale says. And receivers eventually will be small
> enough to embed in smartphones and thousands of other connected
> devices, ranging from watches to dog tags to self-driving cars. “The
> next-generation systems need a lot of synchronization,” he says. “So
> the Internet of Things, which is inevitable and coming, raises the
> bar enormously.”
