An error-free tracking system is disclosed which can operate with a scanning sensor. Beginning with an initialized trajectory for an object, predictions are made with respect to future object position and the sensor produces an error signal representing an error between sensor position (predicted target position) and actual target position at the measurement time. From a sequence of error signals, trend information is extracted and, on the basis of the trend information, the gain of a trajectory correction algorithm is adjusted. Based on the corrected trajectory, a new position estimate is determined. This further estimate is then used for another measurement to produce a further error signal in order to provide for tracking the object or target.
