Position tracking sensor having tapped angled coil

A sensor comprising:

• a core oriented along a first vector corresponding to an axis of the core;
• a coil having windings around the core at an angle to the axis of the core along a second vector;
• one or more middle conductors coupled to the windings to divide the windings into two or more sub-coils about the middle conductors;
• and
• a pair of end conductors coupled to opposite ends of the coil such that signals obtained from the middle and end conductors provide sufficient information to determine roll about the core axis.

• a coil having windings around the core at an angle to the axis of the core along a second vector;
• one or more middle conductors coupled to the windings to divide the windings into two or more sub-coils about the middle conductors, wherein the sub-coils are wound at different angles from one another and either aligned with or at an angle to the axis of the core to provide sufficient information to determine a relative angle between the sub-coils;
• and
• a pair of end conductors coupled to opposite ends of the coil such that signals obtained from the middle and end conductors provide sufficient information to determine roll about the core axis.
