GBAS/SBAS Implementation Workshop




Several States in the Asia/Pacific region have taken the decision to implement GBAS station or SBAS system in the near future. The objectives are to improve safety through geometric vertical guidance for final approach as well as accessibility to regional airports. These benefits combined with the overall PBN benefits will enhance the flight profile and the efficiency of flight operation including fuel saving, CO2 emission reduction, and noise abatement.

The GBAS/SBAS system implementation will create new challenges for States compared to conventional infrastructures. As some other regions have already published flight procedures based on these new systems, it's the right time to learn from their experiences and to understand how they dealt with the challenges and overcame them.

In this regard, ICAO Asia/Pacific Regional Sub Office (RSO) is going to hold a GBAS/SBAS Implementation Workshop in Seoul, Korea from 3 to 5 June 2019. The detailed programme will be posted in the ICAO Asia/Pacific Regional Office webpage soon.


GBAS = Ground Based Augmentation System / SBAS = Satellite Based Augmentation System


Objectives of the workshop:

·      to review requirements of GBAS/SBAS implementation in ICAO publications;

·      to make participants aware of all aspects of GBAS/SBAS implementation;

·      to highlight specificities of GBAS/SBAS procedure design and validation ; and

·      to share experiences and best practices of States and Industry.


Target audience of the workshop:

·         State: regulators, air navigation service providers (ANSPs), flight procedure design office, ATS/CNS/AIM departments

·         Industry: GBAS/SBAS system manufacturers, GBAS/SBAS service providers, avionic manufacturers, flight procedure design company, aircraft manufacturers and users of GBAS/SBAS procedures (airlines)

·         100 participants expected

         *  APAC CAAs/ANSPs participants are given priority and we reserve the right to limit the number of attendees per State​.


Workshop Program:

·         Session 1 - Introduction to GBAS/SBAS

·         Session 2 – GBAS/SBAS Implementation Challenges

·         Session 3 – GBAS/SBAS Implementation in APAC

·         Summary and Outcome of the Workshop



·         ICAO Asia/Pacific Regional Sub-Office
