摘要: A movement information calculating device includes a positioning sensor, a velocity sensor, an attitude sensor and processing circuitry. The positioning sensor is configured to calculate a position of the positioning sensor on a movable body. The velocity sensor is configured to calculate a velocity of the movable body. The attitude sensor is configured to calculate an attitude of the movable body. The processing circuitry is configured to calculate a center-of-gravity position and a center-of-gravity velocity of the movable body by using the position, the velocity, and the attitude, and calculate one of a turning center position and a pivoting position of the movable body by using the center-of-gravity position and the center-of-gravity velocity.

摘要: An attitude angle may be calculated with high precision. In a traveling state calculating device, receiving parts may output data for calculation using positioning signals received by antennas, respectively. A phase difference calculating part may calculate a single phase difference for every base line based on the data for calculation outputted by the receivers. An attitude angle calculating part may calculate an attitude angle using the data for calculation and the single phase difference. A calculating condition determining part may determine a contribution of the data for calculation to the calculation of the attitude angle, corresponding to the component of the attitude angle, based on a spatial relationship between the base line and the positioning satellite.

摘要: The present disclosure is to calculate an estimated position with high precision. A course estimating device 10 includes an angular velocity calculating part 30, a horizontal ground speed calculating part 70 and an estimated position calculating part 80. The angular velocity calculating part 30 measures or calculates an angular velocity of a movable body. The horizontal ground speed calculating part 70 calculates a horizontal ground speed based on an attitude angle, a ground course, and a ground ship speed of the movable body. The estimated position calculating part 80 calculates an estimated position, based on a period of time from a current time point to an estimation time point, the horizontal ground speed, and an integration operation of the angular velocity.

摘要: A slot array antenna that includes radiation, base, and grating plates is disclosed. The radiation plate has a first surface having multiple slots to radiate radio waves, second and third surfaces forming a horn shape, and proximal and distal connecting members. The base plate has first, second, and third surfaces forming a U-shape, and notches. The connecting members of the radiation are removably insertable into the notches to assemble the slot array antenna for the radiation of the radio waves and to suppress noise signals.
