Abstract
An ATC (Air Traffic Control) experiment using ETS-V (Engineering Test Satellite V) was conducted. In the experiment, the position of aircraft was measured by CIS (Cooperative Independent Surveillance) and ADS (Automatic Dependent Surveillance). Data communication and voice communication using NBFM and LPC between ground and air was conducted. The result shows that the positioning accuracy of CIS and ADS is enough to minimize present oceanic separation of aircraft. More than 95% of the controllers participated in the experiment evaluated the quality of voice communication using NBFM as bettr than that of present HF communication. Also 81% of them prefer LPC to HF. An error rate of received characters on aircraft through data communication is less than 2×10^<-4>, which shows that the satellite data link has the possibility of improving oceanic ATC capability.
