Plow guidance system |
摘要 |
A guidance system suitable for use in burying cable uses a previously buried signal-emitting cable to produce a signal along the cable path. A vehicle mounted plow used to plow a second path has a receiver which analyzes signal from the buried cable and determines from it both the lateral direction and the extent of vehicle movement in order to maintain a predetermined lateral spacing of the two paths.
