ITWS provides automated weather information for use by air traffic controllers and supervisors in airport terminal airspace (60-mile radius).
The implementation of ITWS provides the aviation community with a new tool for timely, accurate, short term prediction of weather information," said Bob Eckel, Raytheon's vice-president for air traffic management programs.
The Performance Technologies products used by Raytheon make ITWS radar and sensor data available over an Ethernet/IP network.
Weather systems that will provide data to the ITWS include Terminal Doppler Weather Radar (TDWR), also made by Raytheon; ASR-9 weather channel; Automated Surface Observing Systems (ASOS); Automated Weather Observing Systems (AWOS); Next Generation Weather Radar (NEXRAD); and lightning location and prediction systems.
The award for ITWS is yet another example of Raytheon's broad air traffic control system technology" said C.
The ITWS concept has undergone extensive proof testing since 1993 by the Massachusetts Institute of Technology's Lincoln Laboratory.
The Kansas City system is the first production ITWS system to be commissioned into service.
Automated weather products produced by ITWS for air traffic control include wind shear and microburst detection and predictions, storm cell intensity and direction, lightning information and detailed data of the winds in the terminal area.
The FAA has estimated that the annual delay reduction benefit at Kansas City generated by ITWS to be approximately $7-8 million per year and the total benefit for the full ITWS deployment in the national airspace system to be over $600 million per year.
ITWS achieves this through fusion of data and information from FAA and National Weather Service (NWS) sensors, such as the terminal doppler weather radar, the next generation weather radar (NEXRAD), airport surveillance radar, low level wind shear alert system, automated weather and surface observing systems, lightning detection systems, NWS weather models and aircraft via the meteorological data collection and reporting system.
The ITWS will not only allow ATC to make more informed decisions but will also be available to the airline and airport community allowing for ITWS current situation and predictive information to be used to optimize planning activities that result in decreased delays and increased fuel savings.
The ITWS system has evolved from more than ten years of research and development efforts performed by the FAA, MIT's Lincoln Laboratory and Raytheon.
