Leading core technology program "Development of technology required for multi-beam antenna for public network construction" is from '18 to '22 (51 months) to develop air-based communication and data link through public network construction using multi-beam antenna as a leading program to confirm the possibility, it is being promoted with three unit tasks.

It is required to implement a simulator for performance verification of a multi-beam antenna system using an active phased array antenna suitable for long-distance high-speed communication and to secure public network performance verification technology using a multi-beam antenna. The development of simulator integration and performance analysis simulation technology is required to verify the performance in various operating environments and operating concepts of the air relay network.

KRW 3.05 billion will be invested for 39 months from '19 to '22 in order to configure various simulators consisting of mission equipment, relay equipment, and ground equipment, and develop technology to verify network performance between implemented equipment.
