u-blox' Dead-Reckoning System Enables Nav in Tunnels, Garages
June 3, 2010
u-blox has released a an Automotive Dead Reckoning (ADR) system, to be displayed at Telematics Detroit 2010. The solution has been implemented in in-dash navigation and eCall systems at Tier-1 automotive car electronics suppliers to German auto makers. The solution blends input from GPS satellites with vehicle sensors to determine position even where GPS signals are blocked or weak, u-blox said, such as tunnels and underground garages, and is compatible with virtually any car model or drive train type.
Dead Reckoning capability is becoming a standard feature in all in-car navigation and telematics systems, a market which is predicted to grow at a rate of 20 percent per year, from 20 million units sold in 2010 to 49 million units in 2015, u-blox said.
“Our ADR solution is revolutionary in that it requires no customization and runs entirely on the GPS chip,” claimed Thomas Seiler, u-blox CEO. “The off-the-shelf solution requires minimum integration efforts, reducing risk, cost, and time-to-market.”
In addition to vehicle navigation, ADR supports a growing number of safety, security, and road-pricing applications such as emergency call, pay-as-you-drive insurance, road pricing, and stolen vehicle tracking. The solution ensures uninterrupted navigation and tracking using aiding data from wheel tick sensors and optional gyroscope acquired from the vehicle data bus. It is completely self-calibrating, requiring no pre-configuration.
The system runs on u blox’ automotive-grade GPS receiver chips, which are all AEC-Q100 compliant and manufactured according to the TS-16949 Quality Management Standard.
