• Accurate and reliable position and navigation capabilities of GNSS contribute significantly to the improved safety of aviation.
• In line with ICAO’s policy, Thailand is moving forward with the implementation of GNSS as air navigation and surveillance infrastructures.
• Safety, efficiency, economic, and environmental benefits are expected as results of GNSS implementation.
• Conventional navigation and surveillance infrastructure will be maintained during transitional period.

Performance-Based Navigation (PBN) - is an ICAO framework for defining a navigation performance specification along a route, procedure or in airspace within which the aircraft operating must comply with specified operational performance requirements.

PBN: Harmonizing Modern and Conventional Navigation AidsPBN: Harmonizing Modern and Conventional Navigation Aids
By providing Performance-specific System, operational procedures can be harmonized, even for aircrafts with different equipments.
PBN enables co-use of both conventional and satellite-based navigation aids.

- GNSS is considered a main navigation infrastructure
- GNSS is now becoming a critical component of surveillance system, such as ADS-B
- Unpredicted outage of GNSS services can cause undesired interruptions on aircraft operations.
IntroductionIntroduction

What is RAIM? What is RAIM?
Receiver Autonomous Integrity Monitoring (RAIM) provides integrity monitoring of GNSS satellites for aviation applications.
RAIM utilizes redundancy of satellite signal measurements combined with aircraft barometric altitude equipments to detect any faulty satellite signal based on satellite geometry and probability analysis.
28
Operational Requirements Operational Requirements
- ICAO Annex 10 and ICAO PBN manual require States and Air Navigation Service Providers (ANSPs) to provide timely warnings of GNSS RAIM outages.
- RAIM prediction results are needed daily by pilots, flight dispatchers, air traffic controllers and airspace planners.
- The use of appropriate RAIM prediction services is considered a necessary part of GNSS approvals.
- RAIM prediction is required for en-route, terminal area, and approach operations.
29
Regional RAIM Prediction SystemRegional RAIM Prediction System
- A common, regional RAIM prediction services for a region can proved to be an effective solution.
- By harmonizing RAIM prediction information among States, we will
- enhance seamless air traffic operation;
- provide cost-effective investment solution;
- create a forum to share knowledge and experiences.
30
Regional RAIM Prediction SystemRegional RAIM Prediction System
- ICAO APANPIRG tasks ICAO PBN Task Force to examine the feasibility of establishing a regional RAIM prediction system.
- At GIT 13 and GIT 14, the APEC GIT has expressed its willingness to work cooperatively with ICAO PBN Task Force to support the establishment a regional RAIM prediction services.

Outcome from ICAO APAC PBN TF/6Outcome from ICAO APAC PBN TF/6
ICAO APAC PBN TF/6 Meeting - February 2010, Hong Kong
The PBN TF noted that the proposal is also in line with ICAO APANPIRG Decisions 20/38 and 20/39 which tasks the ICAO PBN Task Force to examine the feasibility of establishing a regional RAIM prediction system and invite ICAO to develop guidance material on establishing common implementation rules and technical standards for GNSS reporting and prediction requirements.
The PBNTF also noted that the 46th DGCA Conference encourages States to support and place priority on the ICAO Task Forces and work programmes for the Asia-Pacific. Proposals on specific mechanisms, such as a regional RAIM prediction service, could also be looked into.
32
8.2.4 The PBN TF was informed that The APEC GNSS Implementation Team (GIT), a team established under the Asia-Pacific Economic Cooperation (APEC) Transportation Working Group, during its thirteenth meeting in 2009, has expressed its willingness to work cooperatively with ICAO PBN Task Force to support the establishment of a regional RAIM prediction service.
The PBNTF also noted with appreciation that Thailand through AEROTHAI is willing to serve as a project coordinator for this important regional activity.
8.2.5 The PBNTF agrees in principle to the establishment of a regional RAIM prediction system and cooperation between the ICAO PBN TF and the APEC GIT.

7.1.5 The PBNTF agrees in principle the establishment of a regional RAIM prediction system and cooperation between the ICAO PBN TF and the APEC GIT. The PBNTF also endorses the Minimal Technical and Operational Requirements for a Regional RAIM Prediction System as followings:
7.1.6 Basic Common Denominator - Noting the differences among different RAIM algorithms on-board different aircraft, a regional RAIM prediction system provided by a service provider, such as an ANSP, should provide a “basic common denominator” RAIM prediction service for “basic” GNSS receivers, such TSO-129 (Fault Detection) and TSO-145/146 (Fault Detection and Exclusion).
34
Outcome from ICAO APAC PBN TF/7Outcome from ICAO APAC PBN TF/7
7.1.7 Prediction Period – A regional RAIM prediction system shall provide prediction for RAIM outage and number of GNSS-satellite availability for a 72 hour period using the latest available GPS NANU.
7.1.8 Approach Operations - A regional RAIM prediction system shall support aircraft approach operations based on RNP APCH (with/without Baro-VNAV) navigation specification. The system shall calculate the predicted RAIM availability for a 72 hour period for specific Aerodromes. The algorithms shall address the RAIM requirements for GNSS receivers operating in Approach operations (±0.3NM). Both the Fault Detection (FD) and Fault Detection and Exclusion (FDE) algorithms shall be provided. The system shall calculate the predicted RAIM availability at the Aerodrome Reference Point (ARP) for baro (pressure altitude) aided and non-baro aided GNSS user equipment at 1 minute intervals or better.

Outcome from ICAO APAC PBN TF/8Outcome from ICAO APAC PBN TF/8
ICAO APAC PBN TF/8 Meeting, May 2011, New Delhi
ICAO PBN TF/8 was informed that AEROTHAI had approved the initial investment for the establishment of the APAC Regional RAIM Prediction System to support ABAS (Aircraft Based Augmentation System), not SBAS and GBAS. Initial operation for the Bangkok FIR is expected to be near the end of 2011. The system would be capable of providing RAIM prediction services for all participating States within the Asia/Pacific Region within 2012.
