Title:
飛行体用航法装置および飛行体用航法
Document Type and Number:
Japanese Patent JP6628254
Kind Code:
B2
Abstract:
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
