Details

Prior to the 1970s, civil aviation aircraft in transoceanic and remote areas can only achieve air-toground communications, air traffic management through short-wave, ultra-short-wave communications, with the introduction of satellite navigation and communication systems, the entire route, and even the worldwide air-to-ground communications and air traffic management services.Aviation satellite communication system can be divided into cockpit satellite communications and cabin satellite communications, the current cockpit satellite communications mainly use the L band, cabin satellite communications mainly use Ka or Ku band.

With the development of satellite manufacturing technology and millimeter wave technology, airborne satellite communication has been developed to the Ka or Ku band,can guarantee the high-speed, reliable and real-time transmission of aircraft health data and cabin broadband. Improve aircraft flight safety, implement aircraft failure analysis, improve aircraft dispatch rate, improve aircraft condition monitoring and health management, improve passenger experience, become the future direction of development and market commanding heights.
