Vehicle Dynamics Sensors for DASthe ground, others arise from geological complexities or are subjective in nature, etc. These errors are discussed and methods of their estimation and, where appropriate, of their treatment are given. The main applications of the CDP-derived velocities are briefly reviewed.
