Experimentation Research and Analysis of Application of Beidou Satellite Navigation System in Civil n (PBN) is proposed by ICAO. Furthermore, in the 36th General Assembly of ICAO, states parties are required to ensure that by 2016, a coordinated approach to the global transition to PBN operation. Accordingly, China’s civil aviation has developed a PBN implementation decision and roadmap. GNSS will
