u-blox 6 ROM-based GPS receiver for automotive applications
NEO-6V supports Automotive Dead Reckoning (ADR), u-blox’ industry proven off-the-shelf Dead Reckoning solution for tier-one automotive customers. u-blox’ ADR solution combines GPS and sensor digital data using a tightly coupled Kalman filter. This improves position accuracy during periods of no or degraded GPS signal.
The NEO-6V provides ADR functionality over its software sensor interface. A variety of sensors (such as wheel ticks and gyroscope) are supported, with the sensor data received via UBX messages from the application processor. ADR is designed for simple integration and easy configuration of different sensor options (e.g. with or without gyroscope) and vehicle variants, and is completely self-calibrating.
