Abstract
An aircraft position measurement system is provided for an aircraft configured to use an artificial satellite configured to fly in a known orbit. The aircraft position measurement system includes a reflector, a distance-angle measuring member, a satellite position obtainer, and an aircraft position calculator. The reflector configured to be mounted on the artificial satellite and reflect an electromagnetic wave in a direction in which the electromagnetic wave arrives. The distance-angle measuring member is configured to be mounted on the aircraft and emit an electromagnetic wave and measure a bearing and a distance to the artificial satellite when seen from the aircraft. The satellite position obtainer is configured to obtain an absolute position of the artificial satellite. The aircraft position calculator is configured to calculate a position of the aircraft based on the absolute position of the artificial satellite and the bearing and the distance to the artificial satellite.
