Project Completion Report of

GNSS Implementation Plan Training in ASEAN (GIPTA 1.0)

 

1.    Background

Global Navigation Satellite System (GNSS), a space-based satellite system standardized by the International Civil Aviation Organization (ICAO), has been introduced in several countries around the world as an alternative and complement to conventional ground-based navigation systems. In order to smoothly implement GNSS in the ASEAN region, it is important to understand the significance and benefits of GNSS and formulate an optimal implementation plan.

 

2.    GIPTA project Overview

The purpose of GNSS Implementation Plan Training in ASEAN (hereinafter referred to as GIPTA) is to train engineers and administrators from ASEAN member countries who will be in charge of preparing implementation plans for the realization of safe and economical introduction of GNSS such as SBAS, which are expected to be used jointly in the ASEAN region. Human resource development will be conducted through training, and upon completion of the project, the entire ASEAN region is expected to be ready for safe, efficient, reliable, and cost-effective air navigation services provided by GNSS.

 

There are three project action items follows.

@       GIPTA Symposium

Managers of civil aviation or those in charge of maintenance of air navigation systems from ASEAN countries will be invited to give a lecture on the current status of GNSS maintenance in the world, issues related to maintenance, and calculation of benefits, and to exchange opinions.

A       GIPTA Training

GNSS maintenance personnel from ASEAN countries will be assembled at the Civil Aviation Training Center (CATC) in Manila, Philippines, and trained on GNSS installation and maintenance procedures, cost effectiveness, certification, and other necessary technologies in addition to GNSS technologies in order to encourage the development of GNSS.

B       Installation of GNSS data analyzer

GNSS data analyzer is to be installed at CATC, Manila, Philippines, in order to actually collect ionospheric data necessary to deepen understanding of GNSS in GIPTA training, and to show the analysis results in the training.

Many of the above comments were received from GIPTA 1.0 participants of ASEAN member states, which led to the planning of GIPTA 2.0.

 

4-2 Project outcome

Through successful completion of the GIPTA training project, it is deepened the understanding by the person in charge of GNSS implementation plan development in ASEAN region for civil aviation GNSS service.  By enrichment of knowledge for GNSS implementation benefit at ASEAN region, it becomes possible to expect civil aviation GNSS implementation for ASEAN airspace in early chance.

With the improvement of air navigation service performance for civil air transportation at ASEAN airspace in early chance, it is expected that the possibility of realization for application chance of regulated high-speed air transportation in an earlier stage.  Accordingly, it is expected that become beneficial for up-grading competitiveness of whole ASEAN regions through contribution for ASEAN region development and economic growth in the future.

Through completion of GNSS implementation plan development skills training (GIPTA) for ASEAN airspace, it is expected that will become to be able to assist reinforce the connectivity of the ASEAN region through the enhancement of regulated exchange in the future.  By that means, it is expected that will be assisted to raise up ASEAN region connectivity.

In addition to those, early-stage civil aviation GNSS introduction for ASEAN airspace, accompanied by enhancement of ASEAN region connectivity will provide sustainable growth assistance measures (SDGs) through high-speed flight civil aircraft fuel consumption reduction or civil aircraft flight noise mitigation and others.

5.    Vision of the future GIPTA activities

 

Civil aviation GNSS introduction at the ASEAN region will provide wide, seamless, safe, and economical air navigation service for civil aircraft flight operation.  GNSS air navigation service introduction at ASEAN airspace will improve air traffic management (ATM) efficiency, especially through the application of SBAS, which will provide a wide and seamless air navigation service for the whole ASEAN airspace.

In GIPTA 1.0, basic GNSS knowledge was to be acquired, and 2.0 will build on this with further updates. It is important for satellite navigation systems to have a bottom-up and common understanding throughout the region.

The GIPTA 2.0 proposal was considered to take into account the requests of ASEAN@countries and to ensure that the next generation of ASEAN countries will benefit from the proposal in common.

The project progression is described as follows.

 

GIPTA1.0 Efficacy

l ASEAN countries gathered to exchange views on the development of infrastructure to improve air traffic safety, and came to a common understanding of the effectiveness of GNSS implementation, one of the said infrastructures. l Through the GIPTA training, ASEAN countries learned the benefits of GNSS implementation and the importance of having a common understanding of GNSS development as an ASEAN region. l Data analysis was conducted using GNSS performance analysis equipment installed in Manila to understand GPS performance and issues.
 


GIPTA2.0 Proposal

l After GIPTA 1.0, ASEAN countries requested the continuation of GIPTA in order to concretize the introduction of GNSS. l Conduct specific training for the early introduction of GNSS, observe equipment in actual operation in Japan, and consider more specific maintenance. l GNSS analyzers will be deployed in three ASEAN countries, enabling data to be acquired simultaneously at four locations in the ASEAN region. This will enable areal GNSS performance analysis across the ASEAN region, making the effects of GNSS implementation clearer. l Implement specific proposals for the development of GNSS (SBAS) in ASEAN.

Consideration for future activity

l Clarify the budget size, maintenance schedule, and various requirements for the realization of specific proposals. l Clarify the concept of establishing a GNSS center in ASEAN.
