Abstract
A position sensor system comprising: a magnetic field generator movable relative to two sensor devices or vice versa. The system has at least one processor adapted with a special algorithm for determining a position of the magnetic field generator in a manner which is highly robust against a disturbance field. A method for determining the position of the magnetic field generator based on a set of equations, in particular a set of linear equations which allows to completely eliminate the external disturbance field.
