This Chip Knows Where You Are Even When Your GPS Doesn't

This chip helps your GPS keep track of your position during those short moments where there is no GPS signal. Eg when you enter a tunnel.
The 3D Dead Reckoning chip uses an accelerometer and other sensors to see if you are still on course.

“Drivers expect car navigation systems to be fast, accurate, and work everywhere, regardless of satellite visibility. As cities expand, construction of more tunnels, multi-level overpasses and park garages is increasing. Our solution meets this challenge head-on; regardless of satellite visibility, our 3D ADR chip shows movement in three dimensions to maintain continuous and accurate positioning in tunnels, stacked highways, multi-level or underground parking facilities,” said Thomas Nigg, VP product marketing at u‑blox.

The technology aids traditional GNSS navigation systems such as GPS, GLONASS and BeiDou by blending them with individual wheel speed, gyroscope and accelerometer information to maintain accurate 3D positioning even when satellite signals are completely lost.

It’s unclear whether the company intends to sell these things to equipment manufacturers or directly to consumers but hopefully we’ll see these on the market soon enough.

    I know my toyota camry’s navigation system works even in tunnel. Maybe this chip is at the heart of it already? I though that by remembering the last position, recognizing the speed of travel and direction of movement (compass) should be fairly accurate to keep one on course. Cars do have the speed of travel input which a cell phone or a handheld device not connected to car’s computer would miss. So this chip may fill in that void.
