Product description

UBX-M8030-Kx-DR is u-blox’ industry-proven off-the-shelf Automotive Dead Reckoning (ADR) solution. u-blox ADR combines concurrent GNSS and sensor digital data using a tightly coupled Kalman filter. This improves position accuracy during periods of unavailable or degraded GNSS signals. ADR supports a variety of sensor combinations, such as wheel ticks, single-axis / 3-axis gyroscope, and single-axis / 3-axis accelerometer. The accelerometer sensor support improves performance during altitude changes without a GNSS signal, such as in tunnels, overpasses, or underground parking. ADR receives sensor data from the vehicle bus via the host processor. This reduces hardware costs since no extra sensors are required for dead reckoning functionality. ADR is designed for simple integration and easy configuration of different sensor options (e.g. DR with or without gyroscope) and vehicle variants, and is completely self-calibrating. The chips also provide improved support for map matching. The UBX‑M8030-KA-DR and UBX-M8030-KT-DR chips provide flash-based 3D-ADR features. The DR chips are pin compatible with standard UBX-M8030 chips. The UBX-M8030-Kx chips are qualified according to AEC‑Q100, and are manufactured in ISO/TS 16949 certified sites.
