Abstract
A status calculating apparatus is provided. The apparatus includes three or more antennas disposed at different positions on a movable body, each antenna receiving positioning signals, correlators 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 for calculating carrier wave phase measurement values, a baseline vector calculating module for calculating baseline vectors based on the carrier wave phase measurement values, and an attitude angle calculating module for calculating a yaw angle for every baseline vector and calculating a representative yaw angle based on the plurality of calculated yaw angles.
