Document Type and Number:
Japanese Patent JP2004536715
Kind Code:
A
Abstract:
A system for providing communication of position information between moving bodies navigating in proximity of each other. Messages can be communicated via the same system. Orientation information is provided by transmitting infrared digital signals that are specific to individual zones around the moving body. By knowledge of the relation between the position of the zones and the specific signals an orientation can be deduced by a receiving body. Distance information is provided by transmitting infrared digital signals from a transmitter at respective power levels, at which power levels the signals comprise information for identifying the specific power level. By knowledge of the relation between the range of the zones and the specific signals a distance from a receiving body to the transmitter can be deduced. Direction information is provided by knowledge of the position of reception zones and signals received.
