U-blox, a Swiss provider of GPS receiver technology, has improved its GPS dead reckoning system solution by including a gyroscope sensor from Epson Toyocom in its reference design.
Adding the gyroscope to the reference design shortens time-to-market and reduces risk for engineers designing applications that require accurate, uninterrupted positioning regardless of GPS signal conditions.
The dead reckoning solution is build around u-blox's LEA-4R dead reckoning GPS module. Epson's XV-8000-CB gyroscope offers improved temperature, shock and vibration stability.
Dead-reckoning applications include vehicle navigation, fleet management, toll systems and other applications that require continuous positioning. An odometer calculates distance traveled and a gyroscope determines turn rate.
This data supplements the GPS data to provide continuous positioning in tunnels, indoor parking facilities, urban canyons and other environments in which it may be difficult to obtain a GPS satellite signal.
The AEK-4R dead reckoning reference design Evaluation Kit will be available in October. More information is available at http:// www.u-blox.com/shop/.
