Project: Autonomous Localization for GPS-denied Aerial Tracking and Reconnaissance (ALLIGATR) Team Abstract: ALLIGATR is an unmanned aerial system designed for navigating and surveying ground ...

No audio available for this content. High-precision GPS, INS and computer vision come together in a single package called VINS to be demonstrated at the Auto.ai show in Berlin on Sept. 25-27.

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 ...

No audio available for this content. Integrations of MEMS sensors with signal conditioning and radio communications form “motes” with extremely low-cost and low-power requirements and miniaturized ...

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 ...

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 ...
