Accelerated Initialization and Calibration Procedure
This section describes how to perform fast initialization and calibration of the UDR receiver for the
purpose of evaluation.
The duration of the initialization phase mostly depends on the quality of the GNSS signals and the
dynamics encountered by the vehicle. Therefore the car should be driven to an open and flat area
such as an empty open-sky parking area. The initialization and calibration drive should contain
phases where the car is stopped during a few minutes (with engine turned-on), phases where the car
is doing normal left and right turns, and phases where the speed is above 30 km/h under good GNSS
reception conditions.
☞
Note that the calibration status of some used sensors might fall back to CALIBRATING if the
receiver is operated in challenging conditions. In such cases, the quality of the fused navigation
will be degraded until optimal conditions are available again for re-calibrating the sensors.
