Claim:
1. A discrete magnetic angle sensor device, comprising: a first magnetic field gradiometer; and a second magnetic field gradiometer, wherein the first magnetic field gradiometer and the second magnetic field gradiometer are of different types of a group of gradiometer types, wherein the group of gradiometer types comprises gradiometer types defined by at least an order of the gradiometer of a group of orders, a gradiometer direction of a group of gradiometer directions, a magnetic field component of the magnetic field of a group of magnetic field components, to which the gradiometer is sensitive, and a type of at least one sensor element the gradiometer comprises of a group of types of sensor elements; wherein the group of orders comprises a first order, a second order, a third order and a n-th order, wherein n is an integer larger than 3; wherein the group of gradiometer directions comprises a first gradiometer direction and a second gradiometer direction different from the first gradiometer direction; wherein the group of magnetic field components comprises a first magnetic field component and a second magnetic field component different from the first magnetic field component; and wherein the group of types of sensor elements comprises a vertical Hall-sensor, a horizontal Hall-sensor, a giant magneto-impedance device, a magnetic field effect transistor, a magneto resistor and a magnetoresistive sensor element.
