New technologies use a variety of inputs to help ensure seamless navigation, even when GPS reception fails because of interference or jamming.

Honeywell has successfully demonstrated multiple alternate navigation technologies for military aircraft. These new products are intended to help ensure seamless navigation — even when GPS signals are blocked, interrupted or unavailable.

For military operations, GPS-jamming — intentional or not — can block vital signals from conveying critical information regarding positioning, navigation and timing (PNT). In these instances, it’s important for military vehicles and aircraft to be equipped with alternative navigation technologies, like celestial

Elon Musk’s brain-machine interface company, Neuralink, conducted a live demo of its technology on Friday, showing a coin-sized device without wires.

The Tesla and SpaceX CEO brought along three pigs, who had varying levels of interest in cooperating. Eventually, the audience was shown real-time neural signals from one of the pigs, which Musk named Gertrude. According to Musk, Gertrude has had the implant for about two months. 

The start-up, which launched in 2016 and is funded primarily by Musk, said it is designing tiny flexible ‘threads’ that are 10 times
