Wireless communication system for agricultural vehicles

A wireless communication system for agricultural vehicles, each vehicle including a global positioning system (GPS), a multi-channel transmitter/receiver module having a limited communication range, and a signal processor connected to the transmitter/receiver module, wherein

• the transmitter is controlled by the signal processor and the transmitter is operable to transmit on a predetermined communication channel a signal including at least a unique vehicle identifier and a signal indicating the current positional coordinates of the vehicle, and
• the signal processor is operable to analyze the signals received from other vehicles within the communication range, the signal processor configured to include a service table comprising vehicles allowed to perform joint operations,
• wherein the signal processor is further operable to determine from the identifier and the positional coordinates data when another vehicle is ready to perform a joint operation with the vehicle, and
• wherein the signal processor determines that a vehicle is ready to perform a joint operation with another vehicle when the unique identifier included in the service table is identified, speed and direction differences are within specified limits, and the communication system is switched to a different communication channel prior to initiation of a joint operation.
