GPS is a godsend when it works. Problem is, there are plenty of places it doesn't work—tall skyscrapers, concrete overpasses, and other huge structures all block the satellite signal you need to navigate. Luckily, Swiss company u-blox just devised a chip that keeps you on course when the satellites drop out, using the most old-fashioned of navigation techniques: dead reckoning.

The u-blox 3D Dead Reckoning chip uses a bevy of accelerometers, gyroscopes, and speed sensors to calculate a car's exact location, no GPS signal needed. By measuring the direction, speed and distance the car has traveled since the last GPS check-in, the chip can tell if the car's still on the intended route, or if it's veered off into lost-land.
