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 ...

Abstract: Autonomous vehicles often operate in complex environments with various sensing uncertainties. On Earth, GPS signals can be blocked or reflected by buildings; and camera measurements are ...

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 ...
