Abstract
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.
