SENSOR DEVICE
First Claim
1. 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°
.
