1. A magnetic-based electronic valve reader for determining a setting of a control valve of an implantable medical device having a magnetic indicator device, the magnetic-based electronic valve reader comprising:
a housing having a display;
a plurality of magnetic sensor devices for use in determining a spatial location and orientation of the magnetic indicator device;
an orientation sensing mechanism, separate from the plurality of magnetic sensor devices, that measures, without reference to data generated by the plurality of magnetic sensor devices, changes in an orientation of the housing; and
a processing system including at least one processing module that receives magnetic sensor values from the plurality of magnetic sensor devices and determines a setting of the control valve of the implantable medical device based upon the magnetic sensor values.
