Posture Estimation Device, Sensor Module, Measurement System, Moving Object, And Posture Estimation Method

A posture estimation device that estimates a posture of a movable body based on acceleration information based on a posture change of the movable body and angular velocity information based on the posture change of the movable body, the device comprising:

• a communication unit that receives a pulse signal, the pulse signal being movement information of the movable body;
• a storage unit that stores the acceleration information, the angular velocity information, and a plurality of posture parameters related to a movement of the movable body;
• a parameter control unit that selects a selection posture parameter from the plurality of posture parameters corresponding to the pulse signal;
• and
• a posture calculation unit that estimates the posture of the movable body by using the acceleration information, the angular velocity information, and the selection posture parameter.
