GPS is a powerful navigation technology, but it doesn’t work as well inside buildings, underground or underwater. Now engineers in Japan have developed and tested an alternative technology that uses ...

Submarines operate for weeks or months beneath the ocean surface, cut off from the satellite signals that guide nearly every other modern vehicle. GPS radio waves cannot penetrate seawater beyond a ...

CHAMPAIGN, Ill. -- The underwater environment may appear to the human eye as a dull-blue, featureless space. However, a vast landscape of polarization patterns appear when viewed through a camera that ...

Scientists have developed an innovative calibration algorithm for the Inertial Measurement Unit (IMU).This algorithm significantly enhances navigation precision by utilizing acoustic signals from ...

With satellite technology advancing fast, and navigation systems reaching an unprecedented sophistication level, we’re witnessing all sorts of cutting-edge product developments on a regular basis. As ...

Two Drexel University mechanical engineers have received a grant from the Office of Naval Research to help develop advanced underwater robots inspired by marine mammals. The project, led by Professor ...

The underwater landscape is not as dull and featureless as it may seem when viewed through the lens of a camera inspired by animals that live in the sea. A new bio-inspired camera shows polarization ...
