DARPA is building acoustic GPS for submarines and UUVs

 

It will utilize undersea sounds instead of satellite feeds.

For all the benefits that the Global Positioning System provides to landlubbers and surface ships, GPS signals can’t penetrate seawater and therefore can’t be used by oceangoing vehicles like submarines or UUVs. That’s why DARPA is creating an acoustic navigation system, dubbed POSYDON (Positioning System for Deep Ocean Navigation), and has awarded the Draper group with its development contract.

The space-based GPS system relies on a constellation of satellites that remain in a fixed position relative to the surface of the Earth. The GPS receiver in your phone or car’s navigation [...]

DARPA is developing smarter, faster armored vehicles

By Andrew Tarantola

The GXV-T will fight smarter than today’s troop transports, not harder.

In response to ever-more dastardly IED technologies, America’s personnel carriers have become lot more resilient over the past few decades. However the ability for armored transports like the MRAP to take a direct blast comes at the cost of their speed, maneuverability, fuel economy, development and construction costs. That’s why DARPA has just awarded contracts to eight institutions for their help in developing a next-generation people mover that’s lighter, faster, smarter and more nimble than today’s trucks.

As you can see in the video [...]
