Computing a magnetic heading

A method, comprising:

• receiving sensor output data from a magnetic sensor;
• measuring a level of noise in the sensor output data;
• determining whether to average the sensor output data based, at least in part, on the level of noise;
• determining an applied sensor output based on the sensor output data;
• computing a magnetic heading based, at least in part, on the applied sensor output;
• and
• sending the magnetic heading to a component of a computing device for use by an application.

A non-transitory, tangible, machine-readable medium having instructions stored thereon that, when executed by a processor, direct the processor to:

• receive sensor output data from a magnetic sensor;
• measure a level of noise in the sensor output data;
• determine whether to average the sensor output data based, at least in part, on the level of noise;
• determine an applied sensor output based on the sensor output data;
• and
• compute a magnetic heading based, at least in part, on the applied sensor output.
