Abstract
The present invention is related to sensor arrangements and particularly to sensor arrangements for symmetric response in a x-, y- and z-coordinate system. The arrangement comprises four gyroscopes with one axis arranged into different directions of sensitivity.
Claims15
A redundant sensor arrangement, for a symmetrical accuracy in an orthogonal x-, y- and z-coordinate system, wherein said arrangement comprises four one axis sensors said sensors being one of a gyroscope or accelerometer, each sensor having one sensitivity axis and each sensitivity axis is directed in one direction, whereby a symmetrical accuracy is obtained in all directions by choosing an angle of inclination (α) between an xy-plane and each of said sensors and the angle of inclination (α) for said sensors is chosen for an interval of 25°-50°, preferably at approximately 35°, i.e. arctan (1/√{square root over (2)})=35.5°.
