PROBLEM TO BE SOLVED: To provide a target motion prediction apparatus capable of changing smooth performance or follow-up performance of a motion predicting filter and predicting motion of a target by accurately determining veering/gear shift using Doppler speed.SOLUTION: A predicted Doppler speed of a target when uniform linear motion of the target is supposed is found out and a Doppler speed variation to be a difference between the predicted Doppler speed of the target and a detected Doppler speed is found out. Further a veering/gear shift level expressing possibility of performance of veering/gear shift in accordance with magnitude of the Doppler speed variation is found out and the motion predicting filter of the target is changed to change followability or smoothness of the filter.

PROBLEM TO BE SOLVED: To output a proper current position in the case that positional skipping has occurred in position data from a satellite navigation system in a position output device for outputting the current position data of an object by using satellite navigation measurement position data obtained by the satellite navigation system.SOLUTION: A predicted position of an object is calculated from the current position at the previous update timing; whether positional skipping has occurred is determined from a position difference between the predicted position and a satellite navigation measurement position updated by a satellite navigation system; and when it is determined that the positional skipping has occurred, a correction position vector for correcting the current position is calculated. The correction position vector is defined as a correction position vector per one update timing in the case that a position difference between the predicted position and the satellite navigation measurement position is eliminated by taking a time longer than an update period; and in the case that it is determined that the positional skipping has occurred, the predicted position corrected with the correction position vector is defined as the current position.

PROBLEM TO BE SOLVED: To provide an abnormality diagnostic device for motor, capable of exactly diagnosing abnormality, such as looseness, generated in a motor with a simple configuration.SOLUTION: A motor 10 includes: a motor driver 20 that outputs a driving signal; a rotational speed detection sensor 30 that detects a rotational speed of the motor; and a controller 22 that outputs a command signal to a motor driver. The controller 22 outputs an abnormality diagnosis command signal that periodically changes motor rotation, sequentially fetching a rotational speed detection signal from a rotational speed detection sensor in a time-sequence manner when the motor rotation periodically changes through the motor driver according to the abnormality diagnosis command signal and diagnoses abnormality on the basis of the fetched rotational speed detection signal.
