State calculation device, mobile body, state calculation method, and state calculation program
Document Type and Number:
Japanese Patent JP6310202
Kind Code:
B2
Abstract:
A status calculating apparatus (10) is provided. The apparatus (10) includes three or more antennas (100A, 100B, 100C, 100D) disposed at different positions on a movable body (900), each antenna (100A, 100B, 100C, 100D) receiving positioning signals, correlators (111A, 111B, 111C, 111D) for calculating carrier wave phase differences for every antenna based on correlation of the positioning signals with a replica signal, carrier wave phase measurement value calculating modules (112A, 112B, 112C, 112D) for calculating carrier wave phase measurement values (ADR A , ADR B , ADR C , ADR D ), a baseline vector calculating module (120) for calculating baseline vectors (AB, BC, CD, DA, BD, CA) based on the carrier wave phase measurement values (ADR A , ADR B , ADR C , ADR D ), and an attitude angle calculating module (121) for calculating a yaw angle for every baseline vector (AB, BC, CD, DA, BD, CA) and calculating a representative yaw angle based on the plurality of calculated yaw angles.
