Projects
Major Research Areas of ENRI
Our institute's mission is to contribute to the realization of policies promoted by the Ministry of Land, Infrastructure, Transport and Tourism. These policies relate to the realization of safe and secure air transportation, appropriate responses to demand recovery and increase, green measures in the aviation sector, and aviation innovation while also focusing on air traffic control and other air safety operations to ensure safe, orderly, and efficient air traffic. In the second mid- to long-term target period (7 years) of the National Institute of Maritime, Port and Aviation Technology which began in FY2023, our institute has set the following four priority topics for research and development to address technical issues in policy promotion and support air safety operations.
1. Improved Air Traffic Safety and Reliability
To expand the air traffic capacity in response to the increase in air travel demand, it is necessary to improve the safety and reliability of air traffic. Accordingly, we are engaged in the research and development of technologies that improve the safety and performance of satellite and ground-based facilities to support current and future aircraft operations, and minimize the impact of facility failures on daily operations.
- Development of safe and available navigation systems by utilizing dual-frequency and multi-constellation GNSS
- Research on Arctic Region Augmentation using Next-generation SBAS
- Construction of Satellite Navigation Backup (APNT) for RNP Deployment in all Flight Phases
- Study on Efficient Enroute Surveillance using Multi-function Antenna for WAM and ADS-B
- Research on New Techniques for Secondary Surveillance Radar (SSR) Mode S
2. Enhancement ATM and Environmental Impact Reduction
As part of efforts to enhance airspace capacity, improve the environment and punctuality, studies on advanced ATM for robust operations, management of new airspace tailored for increasing advanced air mobility and delay reduction at congested airports are underway.
- Flexible Airspace Management to Facilitate Traffic Flow
- Study on Trajectory Coordination Considering Meteorological Information and Air Traffic Flow
- Investigation of Operational Environment for Advanced Air Mobility and Urban Air Mobility
- Time-based management in air traffic control systems considering the aircraft flight phases
3. Advanced Airport Operations
Air traffic control and airport surface management are some of the operations performed at airports. It is necessary to utilize new technologies to streamline these operations and increase the efficiency of runway operations in order to maximize the airport's functionality. To this end, we will perform research and development of technologies to streamline the control tower operations, introduce new surveillance technologies for aircrafts, and establish flexible takeoff and landing routes with low environmental influence.

- Study on the Application of Multi-Surveillance Systems in the Vicinity of Airports
- Study on Advanced Approach and Landing Operations Utilizing GBAS
- Research and development of runway safety improvement technologies based on millimeter-wave radars and cameras
- Research on Improving Safety and Efficiency of Flight Procedures
4. Fundamental Technology Development for ATM/CNS
It is necessary to develop fundamental technologies that contribute to the improvement of sophisticated systems that support air traffic management and to resolve technical issues. Hence, we will focus on the research and development of fundamental technologies to promote digitalization of air traffic and fundamental technologies that support wireless communication with aircraft.
