Abstract: In an Integrated Air Traffic Control System, apparatus, method, and software for sharing vehicle telemetry information between a plurality of sensors of different types and a plurality of users of different types utilizes a communications network coupling together the plurality of sensors and the plurality of users. A plurality of sensor processor devices are respectively coupled to the plurality of sensors, each sensor processor device being configured to receive vehicle telemetry information from its associated sensor, and to convert the receive vehicle information into common vehicle data of a type common to the plurality of users. A plurality of user processor devices are respectively coupled to the plurality of users, each user processor device being configured to receive a demand signal from its associated user and to transmit it to said communications network when it determines that its associated user has a predetermined vehicle profile which requires improvement.
