An apparatus for target location is disclosed. The apparatus includes a housing, which includes a range sensor to generate range data, an image sensor to generate image data, an inertial sensor to generate inertia data, and a processor. The processor is configured to receive the image data from the image sensor and determine a first orientation of the housing and receive the inertia data from the inertial sensor and modify the first orientation based on the inertia data to produce a modified orientation of the housing.
