PROBLEM TO BE SOLVED: To rapidly and surely carry out the re-determination of the integer bias of carrier phase difference in a device for sensing the azimuth and the attitude angle of an object by receiving radio waves from plural position measuring satellites with plural antennas mounted on the object and thereby finding the relative positions of the antennas. SOLUTION: When it is necessary to find the integer bias again in recovering from the interruption of receiving radio waves or in changing the combination of the satellite, the integer bias is directly determined from attitude angle data provided by an IMU attitude calculation part. Thereby, constantly continuous high-precision azimuth and attitude angle information are provided for a user. |
