If you’ve ever tried to use GPS indoors, you know that the signals aren’t easy to acquire in any sort of structure. Now imagine trying to get a satellite fix underwater. Researchers at MIT have a new ...

You’re in a hurry. You’ve rushed to the nearest shopping mall during your lunch hour, looking for one item, one item only. It’s a five-minute task, except for finding the store with the right item—and ...

Tracking drones or whales under the ocean is very difficult because GPS signals break down rapidly in seawater. Typically tracking objects underwater is done using acoustic signaling, but tracking ...

The partnership addresses a critical vulnerability in modern operations: GPS unavailability, spoofing, interference, and jamming. When satellite signals are compromised, autonomous systems and field ...
