Abstract: Apparatus, systems, and methods are disclosed for utility locating with tracking of movement over the ground or other surfaces using a dodecahedral antenna array and a stereo-optical ground tracker having two or more spaced apart cameras and an associated processing element to detect ground features in images from the cameras and determine tracking parameters based on the position of the detected ground features.
