Abstract
A method of tracking a fleet of machines operating at a common worksite is disclosed. The method may include receiving at a central controller an unacknowledged message from communicating devices onboard the fleet of machines, the unacknowledged message including a current location of each of the fleet of machines determined by locating devices onboard the fleet of machines. The method may also include updating a location listing of the fleet of machines with the current location, and repetitively multicasting the location listing to the communicating devices.
