2.4 GUIDANCE

A. Below ground guidance shall be used to guide the linear across the field. This shall be accomplished by utilizing a single wire rectangular lay-out loop that bisects the field on one leg and continues around the end and side of the field to form a return leg. A solar panel shall generate power (collected and stored in a dual battery pack) that activates an oscillator to deliver the cart guidance signal that is carried by the wire loop. The signal emitted from the buried wire shall be detected by the antennae assembly and used to guide and monitor position of the linear unit.

Five antennae are installed on a tubular assembly suspended from the truss rods and mounted in the middle of the free-standing span. Two safety and one reference antennae are located in the middle of the tube and one forward and one reverse steering antenna are installed on opposite ends of the mounting tube assembly. The reference antenna is positioned directly above the buried wire monitoring its signal. As either the forward or reverse steering antenna moves to the left or right of the buried wire it must become “in phase” or “out of phase” in relation to the reference antenna and cause the system to steer back onto the wire. The two safety antennae are located on each side of the buried wire. As long as the wire stays in between these two antennae the system must continue to run.

Should one or the other safety antennae cross over the wire, the safety circuit must be open, and the linear system must shut down. A central pulse box ensures the end of the leading end of the linear system must be intermittently “pulsed” to move thus avoiding an abrupt steering correction and development of excess tension or compression forces.
