Abstract: A change in geoid height is measured easily. A geoid measurement method of the present invention executes an inertial measurement data acquiring step, a comparison data acquiring step, a state variable estimating step, and a geoid calculating step. In the inertial measurement data acquiring step, data related to velocity, position, and attitude angle is acquired as inertially-derived data based on the output of an inertial measurement part having a three-axis gyro and a three-axis accelerometer attached to a moving body. In the comparison data acquiring step, data related to velocity is acquired as comparison data from a source other than the inertial measurement part. In the state variable estimating step, state variables including a plumb line deviation are estimated by using the inertially-derived data and the comparison data to apply a Kalman filter in which the plumb line deviation is included in the state variables.

Abstract: An object of the present invention is to provide a low height type actuator capable of performing a two-dimensional motion. An actuator includes a magnet structure 20 that includes a first array Lx in which the first and second magnets 21 and 22 are alternately arranged in x-direction and a second array Ly in which the first and second magnets 21 and 22 are alternately arranged in y-direction, and first and second wirings 30 and 40. The first wiring 30 crosses the first magnets 21 and 22 included in the first array Lx in y-direction, and the second wiring 40 crosses the first magnets 21 and 22 included in the second array Lx in x-direction. According to the present invention, by making current flow in the first and second wirings 30 and 40, a two-dimensional motion can be achieved. Further, since the first and second wirings 30 and 40 are each a planar wiring that crosses the magnets, height reduction can be achieved.
