Abstract: PROBLEM TO BE SOLVED: To provide a sensor assembling technique equipped with a plurality of gyroscopes detecting angular velocities around different input axes, respectively, capable of enhancing working efficiency and implementing test calibration work simply and inexpensively. SOLUTION: The sensor assembling technique includes a process where all the input axes of gyroscopes 16X, 16Y, and 16Z corresponding to a plurality of substrate elements 12A, 12B, and 12C, respectively, deployed on one flat surface are arranged in the same direction to load, a process where by providing the angular velocity around input axes concerned from a testing machine 28 for the gyroscopes 16X, 16Y, and 16Z, the input axes of which are arranged in the same direction, correction information for calibration of each gyroscope 16X, 16Y, and 16Z is acquired, and a process where after correction information is acquired, the substrate elements 12A, 12B, and 12C are distributed three-dimensionally so as to steer the input axes of each gyroscope 16X, 16Y, and 16Z toward different desired directions.

Abstract: Provided is a position output device for outputting current position data of an object using satellite navigation measurement position data obtained by a satellite navigation system, wherein an appropriate current position is output in cases when a position jump occurs in the positional data from the satellite navigation system. A predicted position of an object is calculated from a current position at a previous update timing, the positional difference between the predicted position and the satellite navigation measurement position updated by the satellite navigation system is used to determine whether a position jump has occurred, and in cases when it is determined that a position jump has occurred, a position correction vector for correcting the current position is calculated. The position correction vector is taken as the position correction vector for an update timing when the resolution of the positional difference between the predicted position and the satellite navigation measurement position takes longer than an update cycle, and when it is determined that a position jump has occurred, the predicted position is corrected to the current position by the position correction vector.
