To properly measure an aircraft position without depending on an external signal.SOLUTION: A position measurement system 100 is constituted by containing an unmanned aircraft 10 and an artificial satellite 20 flying a known track. A reflector 21 for making a laser beam reflect in the incoming direction is mounted on the artificial satellite 20, and a laser ranging angle measurement device 13 for emitting the laser beam and measuring an azimuth and distance of the artificial satellite 20 when viewed from the unmanned aircraft 10 is mounted on the unmanned aircraft 10. A control unit 19 of the unmanned aircraft 10 acquires an absolute position of the artificial satellite 20, and calculates the position of the unmanned aircraft 10, based on the acquired absolute position of the artificial satellite 20, and the azimuth and distance of the artificial satellite 20 measured by the laser ranging angle measurement device 13.SELECTED DRAWING: Figure 3
【課題】航空機の位置を外部信号に依らずに好適に計測する。【解決手段】位置計測システム100は、無人機10と、既知の軌道を飛行する人工衛星20とを含んで構成される。人工衛星20にはレーザー光をその到来方向へ反射させるリフレクタ21が搭載され、無人機10にはレーザー光を発射して当該無人機10から見た人工衛星20の方位及び距離を計測するレーザー測距測角装置13が搭載されている。無人機10の制御部19は、人工衛星20の絶対位置を取得し、取得された人工衛星20の絶対位置と、レーザー測距測角装置13により計測された人工衛星20の方位及び距離とに基づいて、無人機10の位置を算出する。【選択図】図3
