Abstract: A current flowing from a circuit section into an integrated antenna flows through a coil. When a pseudo up-link signal is outputted from a VICS (light) signal processing circuit to check a connection state of an integrated antenna, since a large current flows through a transmitting element for optical beacons of the integrated antenna, a drop voltage of the coil becomes large. When the drop voltage of the coil is within a prescribed range because of divided voltages of resistors, the antenna detection circuit determines that the integrated antenna is normal. In this case, since a large current flows into the coil, a coil having small impedance is used.

The installer starts at a base location and resets the tracking device to cause the tracking device to record this position as the base position.
