Abstract:
1. A method for determining the relative position, velocity, and/or acceleration of a body displaceable in a three dimensional space, wherein a plurality of n linear acceleration sensors, which in each case have a sensitive measurement axis, is provided, wherein said plurality n is at least twelve, wherein the individual linear acceleration sensors are in each case arranged on a position P i which is stationarily fixed with respect to the body and which can be described by a stationary position vector, which indicates the respective position P i from a body-fixed reference point, wherein the linear acceleration sensors are aligned so that their measurement axes are always oriented toward a direction vector wherein the respective linear acceleration sensor and the x, y, z axes of a body-fixed coordinate system passing through the reference point are designated in each case by iε[1, 2, 3, 4, . . . n], wherein the position vectors {right arrow over (r)} i and the direction vectors {right arrow over (Θ)} i are selected so that the rank of a twelve column matrix formed from the column vectors equals twelve, wherein at least one acceleration measurement signal is captured with the linear acceleration sensors, and wherein a position, velocity, and/or acceleration signal is generated for the body from the acceleration measurement signal and data that describe the relative position and orientation of the linear acceleration sensors in the body-fixed coordinate system.
