Electronic Navigation Research Institute (ENRI), an independent administrative agency, as Japan's only national organization in the field of air traffic control has been conducting research on the sophistication of air traffic systems to handle increasing air traffic, improve the safety of air traffic, and preserve the global environment.
To be specific, as explained in ENRI's Research and Development (R&D) Long-term Vision (revised last year) and new mid-term plans starting this fiscal year, the following themes indicate the directionality of ENRI's researches.

• Research and development of advanced in-flight operation
• Research and development of advanced flights near airports
• Research and development of technology and safety connecting the sky and ground

  ENRI conducts research on the Global Navigation Satellite System (GNSS) for the purpose of smoothly introducing into Japan a satellite navigation system that can set flight routes efficiently and flexibly. The results of the research in Japan as a country located in a peculiar geographic environment, in particular, are highly evaluated internationally. ENRI conducts research on trajectory management as well. This research is regarded as a core theme for ENRI's R&D Long-term Vision as well as the Collaborative Actions for Renovation of Air Traffic Systems(CARATS) program of the Civil Aviation Bureau (an agency under the Ministry of Land, Infrastructure, Transport and Tourism). The research for the realization of trajectory management will promote a smooth traffic flow, eliminate air traffic congestion, and reduce CO2 emissions.

  The Great East Japan Earthquake, which occurred on March 11, 2011, left severe damage in Japan. ENRI's Iwanuma Branch lost a part of its laboratory equipment, and in particular, received damage to its experimental aircraft. Considering economic development and a long-term growth of demand for air transportation in Asia, however, ENRI must make efforts toward the restoration of its research facilities by keeping in pace with the reconstruction plan of the country while minimizing the delay of its research caused by the damage. Moreover, in response to meet the world's expectations, ENRI must continue contributing to the safe and smooth development of air traffic in Japan, Asia, and the rest of the world.

  As a matter of course, ENRI invest its resources to researches needed by the social environment while actively returning the results of the researches to society. As always, ENRI appreciates your continuing support for its activities.
