Abstract
Methods and systems associated with aligning reference frames used for tracking an object are disclosed. One embodiment disclosed herein is a method for generating a transform between a first and second frame of reference (FOR) using a sequence of heading values of the object in the first and second FOR. The method comprises providing instructions to orient the object towards one or more external positioning devices in an orienting sequence. The method also comprises obtaining the sequence of heading values of the object in the second FOR using an onboard sensor and obtaining a sequence of position values of the object in the first FOR in accordance with the orienting sequence and using the one or more external positioning devices. The method also comprises deriving the sequence of heading values of the object in the first FOR using the sequence of position values.
