ATC Spectrum Engineering Services represents the United States (U.S.) in meeting of the ITU and ICAO which require frequency spectrum engineering expertise and deal with civil aviation interests. These meetings address various issues, but all develop policy, technical procedures, and criteria concerning the use, sharing, management, or allocation of the radio frequency.
ATC Spectrum Engineering Services provides the U.S. member to the ICAO's FMSG which meets once or twice a year to assist ICAO in formulating ICAO positions on various frequency management related issues. ATC Spectrum Engineering Services represents the FAA and TSC in IRAC, which meets twice a month under the auspices of NTIA, whose basic functions are to develop policies, programs, and procedures, and technical criteria pertaining to the allocation, management, and use of the radio frequency spectrum. The definition and establishment of frequency coordination procedures with Canada and Mexico are important aspects of the project.
ATC Spectrum Engineering Services is active in a number of IRAC ad hoc groups addressing a wide variety of spectrum management issues such as preparation for World Radiocommunication Conferences (WRC), improved utilization of Government frequency resources, and providing spectrum resources for new system developments and services supporting current and future civil aviation needs.
