Abstract:	Increasing integrity of GNSS (whether current or modernized ones) service is a key technology driver in Global Air Navigation Plan of International Civil Aviation Organization (ICAO). This includes supporting approaches to landing with lateral as well as vertical guidance to achieve an increased level of safety and other operational benefits. This project is to identify and develop key technologies about Advanced RAIM (ARAIM) concepts. Most of the work is focused on the availability and feasibility of a Dual Frequency Multi-constellation (DFMC) ARAIM, with highlight on China and its surrounding area. This report focuses on the ARAIM when BDS (Phase 3)/GPS is concerned. The results will be crossvalidated with those in terms of GPS/Galileo. In particular, this report will present two results: (1) the simulation results of VPL and HPL from ARAIM with respect to signal-in-space error (URA) which is set to 2.4 m; (2) the availability results of ARAIM of every single user. Note that ARAIM using only BDS (Phase-3), with single and dual frequency signals, will be reported in (1) and (2); and (3) ARAIM evaluation results using combined GPS/BDS.
