PROBLEM TO BE SOLVED: To provide a measurement apparatus in which a lateral velocity and a sideslip angle at a designated position within a mobile can be calculated accurately in real time, and a measurement method.SOLUTION: A measurement apparatus comprises: a relative position calculation section 12 which calculates relative positions of a first antenna 10 and a second antenna 11; an attitude angle measuring section 13 which measures an absolute attitude angle of a mobile 2; a calibration section 14 which adjusts the absolute attitude angle; a mobile velocity measuring section 15 which calculates a velocity of the mobile 2; an acceleration/angular velocity measuring section 16 which measures an acceleration and an angular velocity in a triaxial direction through an IMU 20; a velocity/attitude angle calculation section 17 which calculates an attitude angle and a velocity of the mobile 2 in real time by performing strap-down arithmetic operation; a designated position coordinate velocity calculation section 18 which calculates a velocity at position coordinates designated within the mobile 2; and a lateral velocity/sideslip angle calculation section 19 which calculates a lateral velocity and a sideslip angle at the position coordinates designated within the mobile 2 in real time. |
