u-blox' dead reckoning solution, powered by the LEA-4R GPS module, is ideal for applications that require continuous positioning such as vehicle navigation, fleet management and toll systems. 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.
"u-blox' LEA-4R dead reckoning GPS module enables 100% road coverage. Epson's XV-8000-CB gyroscope offers improved temperature, shock and vibration stability," said Karsten Tietz, VP Sales EMEA at u-blox. "The combination of Epson's high performance gyroscope with our highly flexible and compact LEA-4R module provides engineers with a high performance solution that will significantly speed up their design cycle and ease GPS integration," Mr. Tietz added.
Dieter Liesabeths, VP Sales & Marketing at Epson Europe Electronics GmbH, said: "u-blox' choice of our gyro sensor for this reference design underlines our sensors' superiority in key characteristics like linearity, zero-point-drift and temperature stability, as well as small size. The use of the XV-8000CB gyro sensor in u-blox' dead reckoning reference design is fully in line with our strategy to aggressively address the toll collection and navigation market with the gyro".
The AEK-4R dead reckoning reference design Evaluation Kit is available from October from u-blox official distributors and from u-blox' online shop.
