Satellite-Free Navigation

June 21, 2011

This system, intended for phones and other mobile devices, can determine location in the absence of GPS or Wi-Fi signals. A dedicated processor combines input from three sources: a gyroscope, a sensor that measures Earth’s magnetic fields, and a silicon-based air pressure sensor that estimates altitude. This allows the processor to use dead reckoning to estimate the device’s position relative to its last good GPS or Wi-Fi fix.

Product: 10 DoF sensor (evaluation board shown)
Cost: $5.90 (in volume)
Availability: Late 2011

Companies: STMicroelectronics
