Submission + - Dead Reckoning For Your Car Eliminates GPS Dead Zones 3

cartechboy writes: We've all been there. You're relying on your vehicle's built-in navigation system to get to that meeting downtown, but then suddenly the car loses the satellite signal due to the concrete skyscraper canyon you're in--and you're about to be late. Swiss semiconductor manufacturer U-Blox thinks it has the solution with 3D Automotive Dead Reckoning, or 3D ADR for short. It's a new navigation chip that uses the vehicle's built-in sensors to track speed, horizontal movement, and elevation. The 3D ADR system measures movement in three dimensions, letting the navigation system can keep track of the vehicle's location even when it loses its connection to GPS satellites. Imagine never having to see your navigation screen saying connection lost again. In an age where our phones have accelerometers and compasses, it's amazing your car is still trying to catch up, right?

  • Drive into a tunnel, or under the EL in Chicago, it figures it out and plots by DR.
    It knows where the tunnels are, and where they come out, and simply times your journey to guess.

    They have been advertising [] job openings in this field
    for some time, perhaps looking to improve the feature to handle mountain and city canyons where getting a clean signal
    can be difficult.

  • ...does it eliminate the Slashdot Beta?

  • Using cheap gyros/accels will give you good DR accuracy for about a minute at driving speeds. Anything more than that requires an order of magnitude increase in the cost of the sensors. The costs will come down with time, but don't expect the GPS free option on your cell phone to give you much benefit in the near term.
