APVI/II flight procedure is to rely on a satellite positioning system to provide navigation guidance instead of relying on the ground navigation aids. China has built its own Beidou II satellite navigation system, but the current vertical navigation accuracy has not reached the requirements for APVI/II procedure. Therefore, integrating the Beidou II satellite positioning and barometric altitude improves the Beidou II vertical altitude accuracy to satisfy APVI/II operation requirement. Global networking construction of Beidou system will be completed in 2020. Its GEO satellite sends satellite-based enhancement signal, which enables wide application of APVI/II. This paper analyzes the algorithm and safety of the flight procedure based on combined navigation of Beidou II/barometric altitude, demonstrating the feasibility of application of Beidou II system in APVI/II flight procedure in China.
