Turns out, the over 150 year old London Underground is an ideal testing spot for some new sensors. Researchers are trying to come up with more robust GPS that will work deep underwater.
A ‘quantum compass’ won’t rely on our current global navigation satellite systems. Via The Guardian:
The ideal place to test it is the London underground, Cotter and his team have discovered. “We are developing very precise new sensors using quantum mechanics, and these are showing great promise in the laboratory,” he told the Observer last week. “However, they are less accurate in real-life settings. That is why we are taking our equipment to the London underground. It’s the perfect place for smoothing out the rough edges and getting our equipment to work in real life.”
Until we get the quantum compass, GPS is still the way to go. Check out some of these projects from the Adafruit Learn System:
