A right inductive coil is coupled to a vehicle at a first location offset from the vehicle's centerline for generating a first signal in response to an electromagnetic signal in a guide wire beneath the vehicle. Similarly, a left inductive coil coupled to the vehicle opposite the right coil relative to the centerline for generating a second signal in response to an electromagnetic signal in the guide wire. A signal comparator receives the signals and generates a guidance signal representative of the combination of the signals. Also, a position antenna is movably mounted in the vertical dimension on the vehicle for generating query pulses and detecting echo pulses from transponders embedded in a test track.

[ What is claimed is:] [1.] A position system for a remotely controlled vehicle disposed on a track having position transponders embedded therein, comprising:a vehicle controller (VCON) mounted in the vehicle;a position antenna movably mounted on the vehicle between a first vertical position above the track and a second vertical position higher above the track than the first, the position antenna being electrically connected to the VCON for transmitting a query pulse and detecting an echo pulse from one of the transponders.
