Abstract
Devices comprising sensor arrangements for providing first field information defining at least parts of first fields and for providing second field information defining at least parts of second fields are provided with updaters for updating parameters of the first and/or second fields via criterion-dependent iterations, to become more reliable and user friendly. The fields may be earth gravitational fields and/or earth magnetic fields and/or further fields. The parameters comprise magnitudes of the fields and dot products of the fields. The criterion-dependent iterations comprise magnitude functions and dot product functions. The magnitude functions define new magnitudes being functions of old magnitudes and of updated magnitudes and the dot product functions define new dot products being functions of old dot products and of updated dot products. The criterion-dependent iterations further comprise one dimensional criteria and/or rectangular, hyperbolic and/or topped-off hyperbolic two dimensional criteria all defining threshold values.
