A miniature, cheap, and high-precision gyroscope developed at the University of Michigan can help unmanned aerial vehicles and autonomous cars stay on track without a GPS signal.
“Our gyroscope is 10,000 times more accurate, but only 10 times more expensive than the gyroscopes used in your typical mobile phones. This gyroscope is 1000 times cheaper than much larger sensors with similar characteristics, ”said Halil Najafi, professor of engineering at the University of Michigan and professor of electronic engineering and computer science.
Most smartphones contain sensors - gyroscopes to determine the orientation of the screen and help the electronic device determine the direction of rotation, but their accuracy is low. For this reason, telephones often incorrectly indicate in which direction the user is looking while working in navigation applications.
