Abstract: Optical ground tracking apparatus for use with buried object locators or other instruments or devices are disclosed. In one embodiment, a buried object locator includes a locator module disposed in our coupled to the housing to sense a buried object based on emitted magnetic fields, and a surface tracking module for determining motion information of the buried object locator based on light reflected from a tracking surface.
