1. A method, comprising:
- initializing a portable device by storing position and orientation data in a memory of the portable device, the position and orientation data indicating a position and orientation of the portable device within a local coordinate system associated with a target structure;
detecting movement of the portable device;
determining movement data based on the detected movement;
determining a spatial relationship of the portable device relative to the target structure based at least partially on the position and orientation data and the movement data;
when the spatial relationship is within a first threshold distance of a target component, activating a first indicator at the portable device; and
when the spatial relationship is within a second threshold distance of the target component, activating a second indicator at the portable device, wherein the first threshold distance is different than the second threshold distance, and wherein the first indicator is distinct from the second indicator.

Abstract
Position determining systems and methods are provided. A particular portable device includes a calibration component to communicate with a local positioning system to determine an initial position and orientation of the portable device within a local coordinate system associated with a target structure. The portable device also includes at least one movement sensor to detect movement of the portable device. The portable device further includes a processor to determine a measured position and orientation of the portable device based on the initial position and orientation of the portable device within the local coordinate system and based on the detected movement of the portable device.
