Korean SBSP Pilot System and High-Powered WPT Technology

In Korea, two research institutes are preparing for the long-term goal of the SBSP system. KERI developed a 4.8kW Wireless Power Transmission (WPT) system tracking a moving target 50m ahead in real-time. Furthermore, KARI proposed the first and second pilot systems for SBSP in collaboration with KERI at the 74th and 75th International Astronautical Congress. The WPT payload developed and applied to the design of the pilot system can transmit more than 48W continuous microwaves per kg. The pilot systems plan to demonstrate kW-level power transmission between two satellites and between satellite to the ground station accordingly.
