Cutter suction dredger reamer does not have accurate positioning system of tidal observation

The utility model relates to a cutter suction dredger reamer does not have accurate positioning system of tidal observation, characterized by: including land base station, first group and second group RTK real time kinematic control system, angle sensor and information processing system, the land base station is establish on land through known control point, first group and the RTK real time kinematic control system of second group provide the data source of reamer 3D localization respectively, ship portal crane top is inhaled at the hank to the first RTK real time kinematic control system of group rigid coupling, the RTK real time kinematic control system of second group installs at the driver's cabin top, the angle sensor rigid coupling is on reamer bridge tail end plane, information processing system installs in the ship driver's cabin is inhaled to the hank. Beneficial effect: utilize the precision measurement of the real -time three -dimensional coordinate of RTK real time kinematic control system realization hull fixed point, the coupling phase is answered the hull parameter to realize no tidal observation reamer and is exactly transferred the 3D localization technique.
