As Japan's only research institute in the field of air traffic management (ATM), the Electronic Navigation Research Institute (Independent Administrative Institution), or ENRI, provides technical and theoretical support mainly for the administrative policies of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT).
    Aviation, as global transport system, plays an important role to connect city pairs domestically and internationally with high speed and comfort in Japan. It is very important for us to secure safe and efficient air transport as we aim at sustainable economic development. In this context, ENRI has been aggressively tackling researches on efficient use of airspace, capacity enhancement in the congested airports, safety enhancement of air transport.
    The research on GNSS is the study so as to safely and efficiently introduce into Japan the satellite navigation system which has been widely accepted internationally. This research result has been highly appreciated among international community as Japan is situated in geographically unique location from ionospheric standpoint. In the publicized ENRI's long term research vision, research on trajectory management is placed as center core. This study will realize 4-dimentional navigation without jeopardizing the specific characteristic of air transport, swiftness, and enhance smooth air traffic flow, reduce air traffic congestion in air and on ground, and is expected to reduce CO2 emission.
    In order to realize efficient air transport as a convenient means of public transport that can be used safely and securely, ENRI is committed to fulfilling its mission as Japans' core research institute in air traffic management and responding to public expectation by returning the results of its research to society and promoting further efficiency in administrative management. We sincerely request the continuous support of all concerned.
