1. A redundant sensor arrangement for a symmetrical accuracy in an orthogonal x-, y- and z-coordinate system,wherein said arrangement comprises at most four single axis sensors, each sensor is one of a gyroscope or an accelerometer, each sensor has one sensitivity axis and each sensitivity axis is directed in one direction, such that a symmetrical accuracy is obtained in all directions by choosing an angle of inclination (α

  • ) between an xy-plane and each of said sensors, wherein the angle of inclination (α

    ) for said sensors is chosen for an interval of 25°

    -50° and

    a sum of signals from each sensor is approximately zero (0).
