1. Atomic GPS
Because of the high costs of maintaining satellites for the Global Positioning System (GPS), DARPA has been researching other ways to locate a person or device more accurately and without the satellites. Research on atomic physics details how the Earth’s magnetic field acceleration and position is effecting individual atoms, so that GPS systems could use chip-scale combinatorial atomic navigation, C-SCAN, and Quantum Assisted Sensing, QuASAR, to find a person or device’s location on Earth that is 1,000 times more accurate than any current GPS system.
