摘要： A ground tracking system including a ground follower assembly for use with a locator or other device for determining position, motion, and/or orientation information is disclosed. The ground follower assembly may include a wheel assembly coupled to a locator and configured to swivel and/or pivot relative to an antenna node of the locator to generate signals for use in determining position information during a locate operation, such as from a sonde array.
