PROBLEM TO BE SOLVED: To provide an unmanned aircraft inertia measurement module which is favorable in a vibration isolation effect.SOLUTION: Devices such as inertia sensors which are high in demands to vibration performance are aggregated to a second circuit board 6, a vibration characteristic of an inertia measurement module is improved by installing a damper, and a natural mechanical vibration frequency of the inertial measurement module is set at a value which is further lower than a vibration frequency which is not associated with a variety of kinds of motions generated by an aircraft. By installing a first vibration isolation pad 3, vibration caused by an unmanned aircraft to the inertial sensor is quickly attenuated, vibration which the inertial sensor receives after the use of damper is attenuated up to a value not higher than 30% of vibration at a non-use of the vibration isolation pad when the unmanned aircraft generates a frequency not lower than 50HZ, an influence to the inertia sensor caused by a motion vibration frequency of the unmanned aircraft is reduced to the minimum, and the stability of measurement by the inertial sensor is improved.SELECTED DRAWING: Figure 4

    【課題】防振効果が好ましい無人航空機慣性計測モジュールを提供する。【解決手段】慣性センサーなど振動性能への要求が高いデバイスを第2回路板6に集成し、ダンパーを設置することによって慣性計測モジュールの振動特性を改善し、慣性計測モジュールの固有機械振動周波数を、航空機が発生する各種の運動に関連しない振動周波数よりはるかに低いものとする。第1防振パッド3を設置することによって、無人航空機による慣性センサーへの振動を迅速に減衰させ、無人航空機が50HZ以上の周波数を生じたとき、ダンパー使用後に慣性センサーが受ける振動を、防振パッド未使用時の振動の30%以下まで減衰させ、無人航空機の動作振動周波数による慣性センサーへの影響を極大に減少し、慣性センサーによる計測の安定性を向上させる。【選択図】図4
