A review for space-based ADS-B

As an important technology of air traffic control in the future, space-based ADS-B technology can overcome the difficulties of ground equipment deployment in desert, ocean, polar and other places. The space-based ADS-B technology has the characteristics of a wide range of reconnaissance and reception, which can cover the whole world, and relevant studies have been carried out in many countries. According to the frontier characteristics of ADS-B technology, the research progress of ADS-B technology is investigated. First of all, the principle and related research of ADS-B arc summarized. Secondly, the key technologies of ADS-B reception on board arc reviewed from four aspects: antenna technology, radio frequency circuit technology, signal processing and constellation design method. Finally, the application of ADS-B data and its future development prospect arc described.
