Mitsubishi Electric Corporation is pleased to announce that a subsidy has been awarded for the technology development task "Development of Internationally Competitive Full Digital Communication Payload" (hereinafter referred to as "this technology development"), for which our company was selected as the representative organization. This task is part of the "Development and Demonstration of Technologies for Internationally Competitive Communication Payloads" (Field: Satellites, etc.) (hereinafter referred to as "this theme"), one of the public offering themes in the second phase of the Space Strategy Fund (Note 1) implemented by the National Research and Development Agency Japan Aerospace Exploration Agency (JAXA). We will aim to develop a "full digital communication payload" with flexible communication and high security. In recent years, there has been a growing demand for satellites whose functions and performance can be flexibly modified even after launch, in accordance with user requirements. For geostationary communication satellites, which offer excellent wide-area coverage, broadcast capabilities, and disaster resilience, digital communication payloads (Note 2) that utilize digital signal processing technology and can adapt to fluctuations in satellite communication demand by time zone or region through software rewrites are attracting attention, with development and manufacturing primarily progressing in Europe and North America. In this technology development, Mitsubishi Electric will leverage the know-how cultivated through the development of the "Technical Satellite 9" ordered by JAXA to develop a full digital communication payload with flexible communication and high security. Specifically, we will realize a payload that expands the communication target area to the entire visible range of the Earth with a DRA (Note 3) antenna and can flexibly change the beam irradiation area using DBF (Note 4) communication technology, which forms radio wave beams in arbi
