Title:
SENSING SYSTEM
Document Type and Number:
Japanese Patent JP2023132989
Kind Code:
A
Abstract:
To accurately estimate the attitude or motion state of a flying object.SOLUTION: A sensing system comprises: a first reference pressure room within a flying object which is a space connected via a first communication passage to a plurality of holes for measuring the reference pressure that are provided on the surface of a tip on the front side of the flying object; a second reference pressure room within the flying object which is a space connected via a second communication passage to the plurality of holes for measuring pressure that are provided on the surface of the tip; a plurality of differential pressure sensors that are provided in the second communication passage and detect the differential pressure between the pressure on the side of the holes for measuring pressure and the pressure on the side of the second reference pressure room; an absolute pressure sensor that is provided in the second reference pressure room and detects an absolute pressure; and an estimation unit for estimating the attitude or motion state of the flying object on the basis of the output of the differential pressure sensor and the output of the absolute pressure sensor.SELECTED DRAWING: Figure 2
