Contactless power transfer system for high speed rail
The pantograph used for high-speed railway power supply has a risk of exposure to the outside of high-voltage wires. In addition, due to friction wear, the pantograph and tram line need to be replaced periodically, so improvement is also needed in terms of economic feasibility. In particular, most of the failures of KTX are not the failure of the train itself, but the problem of power supply.

- Develop a new high-safety, high-efficiency power transmission system that supplies power without contact while driving.
As of 2012, the Korea Railroad Corporation and the development of high-speed railway wireless power collection system are underway.

- Development of technology for predicting the degree of damage to surrounding areas caused by noise generated by railways.
- The frequency characteristics of railway vehicles differ depending on external factors such as operating speed and curve section even if they are of the same type, so the railway noise prediction and vibration prevention system using surrounding environmental information was developed.
Simulation of Noise Reduction through the Installation of Soundproof Wall
The speed of the train increases and aerodynamic phenomena are remarkable, especially in countries with many tunnels such as Korea, the problem of generating micro-pressure waves due to high-speed driving occurs. Micropneumatic waves emit shock noise at the exit of the tunnel, generating explosion sound and vibration. In particular, since they are low frequencies, they cannot be blocked by soundproof walls and the transmission range is more than 100m from the tunnel exit.
- Develop a tunnel system for suppressing the generation of micro-pressure waves and development of train frontal shape optimization technology.

Next Generation GNSS
As an early research field worldwide, we have developed prior research and systems on the standard technology of the Next Generation GNSS to overcome the shortcomings of current GPS and implement various services.
Recently, the technological convergence of aeronautical, electronic and transportation engineering has led to innovative changes in aircraft navigation and air traffic, as well as personal location and automotive navigation systems. However, the current satellite navigation system is designed to be suitable only in an aviation environment where there are no obstacles to radio reception and no reflection, so accurate location and automatic navigation are almost impossible in an urban environment where buildings and other buildings do not receive satellite signals. In addition, existing GPS signals have various problems such as being unable to measure their position when interference or jamming signals occur.
Future satellite navigation systems that converge with advanced communication technologies are expected to revolutionize the shortcomings of current GPS in the near future.
Like mobile communication technology, it receives signals and locates them indoors. It is expected that the performance and utilization of the system will be greatly improved by developing super-resolution technology that can accurately measure its location even in urban environments and introducing robust technologies for interference and jamming.
Detection and tracking system
Radar and imaging detection and tracking systems are critical in a wide range of navigation and navigation systems, especially military, aviation, space exploration, remote sensing, autonomous navigation, unmanned exploration, ITS, and air traffic systems.
Research and development of technologies that significantly improve the accuracy of detection and tracking systems while minimizing the amount of measurement data for information detection through the realization of super-resolution and compressed sensing technologies expand the application of detection and tracking systems to all ground traffic and air detection areas.
CNS/ATM
The next generation of navigation systems, which will become the international standard for global aviation systems by 2025, will enable automatic traffic management based on state-of-the-art communications, navigation and observation systems.
Communication systems are expected to evolve using advanced mobile communication technology to enable the establishment of various mobile communication networks between aircraft as well as simple ground control centers (standardization in progress).
The navigation and observation systems are being developed through the technology that provides direction and distance information and information necessary for precision landing so that the aircraft can safely fly to its desired destination and the technology that maximizes air traffic efficiency by identifying the flight location and flight trajectory of real-time aircraft for smooth communication and safety of aircraft.

UAV WPT system can be used in drones for reconnaissance and data collection due to the advantage of maximizing the range of movement without refilling fuel.
- Develop a system that wirelessly supplies energy from the ground for drones (or aircraft) using lasers or microwaves

It can contribute significantly across the automotive and IT industries, and it can also enable faster implementation of future technologies by overcoming technological challenges that have yet to be addressed.
Development of key technologies needed to advance existing positioning and navigation technologies through advanced research and development of next-generation GNSS systems with improved accuracy and utilization. It contributes to precision navigation in urban environments, indoor three-dimensional location and service, and strengthening of national infrastructure and defense systems, which were not possible due to the technical limitations of existing GNSS.
It contributes to the realization of eco-friendly aviation services along with the efficiency and economy of the aviation system by enhancing the safety of air traffic, expanding air capacity, reducing delay time, and reducing operating costs.
