ITU Spectrum Protection | for ADS-B in Space

The International Telecommunication Union (ITU) granted primary allocation of the 1090 MHz frequency band for the reception by satellite of ADS-B signals from aircraft. The decision, made during the World Radiocommunication Conference (WRC-15) in Geneva, Switzerland, protects this essential frequency for real-time flight tracking and global surveillance of aircraft through ADS-B over satellite. This important step will extend air traffic surveillance coverage of equipped aircraft to 100 percent of the earth’s surface, previously only 30 percent.
