To provide a flight vehicle-purpose navigation device that can properly correct posture errors even when using a general-purpose inertial measurement device of low accuracy.SOLUTION: A flight vehicle-purpose navigation device, which is mounted to a fight vehicle, comprises: a detection device that detects inertia force acting on the flight vehicle; a first estimation unit that estimates a first error serving as at least a part of error ingredients between an initial setting posture of the detection device and a mounting posture relative to the flight vehicle on the basis of a result of a correction by gravity acceleration with respect to acceleration detected by the detection device when the flight vehicle stands still; and a positioning unit that derives a position and velocity of the flight vehicle on the basis of the initial setting posture in which the first error estimated by the first estimation unit is removed.SELECTED DRAWING: Figure 5

    【課題】汎用の低精度な慣性計測装置を用いた場合であっても姿勢誤差を適切に補正することができる飛行体用航法装置を提供する。【解決手段】飛行体に搭載される飛行体用航法装置であって、前記飛行体に働く慣性力を検出する検出装置と、前記飛行体の静止時に、前記検出装置によって検出された加速度に対する重力加速度による補正の結果に基づいて、前記飛行体に対する前記検出装置の初期設定姿勢と取付姿勢との誤差成分のうち少なくとも一部である第1誤差を推定する第1推定部と、前記第1推定部によって推定された前記第1誤差が除去された前記初期設定姿勢に基づいて、前記飛行体の位置および速度を導出する測位部とを備える飛行体用航法装置。【選択図】図5
