A research group DAPRA, which helped to invent the Internet and also aided in the creation of the GPS is now developing a new navigation and positioning technology.
Since 2010 DAPRA has been creating a new system which does not require satellites to pinpoint a location. With just an eight cubic millimeter chip, they are able to detect the position, time and direction. This new technology is also aimed at being used underwater where satellites do not reach.
They fear to be over-reliant on GPS. Amongst it is that the enemy could scramble the GPS signal as happened in South Korea not long ago. Hence, such a technology which is a chip containing 3 gyroscopes, 3 accelerometers and an atomic clock creates an autonomous navigation system.
DAPRA looks towards using this technology to replace GPS in small caliber ammunition or for surveillance purposes.
