Abstract
A magnetometer unit which may be incorporated in an electronic device receives first magnetic response data from a first magnetic sensor and second magnetic response data from a second magnetic sensor displaced from the first magnetic sensor. The magnetometer unit generates a composite response surface representation from the first magnetic response data and the second magnetic response data, and stores the composite response surface representation in a non-transitory memory.
