The invention relates to a dynamic gyroscope north-finding calibrating device. The dynamic gyroscope north-finding calibrating device comprises sighting equipment and at least one set of to-be-sighted equipment. The dynamic gyroscope north-finding calibrating device has the advantages that by adopting a GNSS (global navigation satellite system) all-weather real-time positioning and orienting function, and utilizing an RTK (real-time kinematic) technology and splitting type orienting technology, the high-accuracy orienting function can be realized in a shorter base line; by combining the high-accuracy photoelectrical sighting equipment, the high-accuracy true north orienting is realized; the dynamic gyroscope north-finding calibrating device can be distributed in an open area to be calibrated, and the constraint by the land is avoided; when the equipment works for a long time, the calibrating is not needed; the maintenance cost is low, and the high-accuracy north-finding orienting can be realized in short distance; the dynamic gyroscope north-finding calibrating device can be used for calibrating gyroscope equipment with different accuracy, and the calibrating is rapid; therefore, the dynamic gyroscope north-finding calibrating device can be widely applied to the technical field of testing and calibrating of gyroscopes.
