Japan Radio, SKY Perfect JSAT, and Sharp Collaborate to Promote Ministry of Defense's "Development and Demonstration of Resilient Communication System Compatible with Multi-Orbit"

Japan Radio Co., Ltd. (hereinafter, JRC), SKY Perfect JSAT Corporation (hereinafter, SKY Perfect JSAT), and Sharp Corporation (hereinafter, Sharp) will collaborate to develop and demonstrate a next-generation communication system, advancing the Ministry of Defense's public announcement "Development and Demonstration of Resilient Communication System Compatible with Multi-Orbit" (Note 1), for which JRC was selected on February 4, 2026.

This public announcement aims to enhance communication infrastructure resilience (Note 2) and communication reliability, recognizing the growing demand for communication in disaster prevention and defense sectors and the need for stable communication even under various conditions such as natural disasters and unforeseen events. It seeks to establish a next-generation communication system that combines and utilizes GEO, MEO, and LEO (Note 3) satellites. This will enable multi-orbit capability by establishing control technology for seamless switching among satellite communication systems, which are currently used individually for each satellite type.

During the implementation period until March 31, 2028, JRC will primarily oversee the overall project coordination, SKY Perfect JSAT will focus on building seamless communication networks, and Sharp will drive the development of multi-orbit compatible satellite communication user terminals (Note 4). The three companies will verify the development of a communication system compatible with multi-orbit GEO, MEO, and LEO satellites and the enhancement of communication network resilience.

Through this demonstration, the three companies aim to improve communication reliability under various conditions, including disasters and emergencies, contributing to the maintenance of social functions and the assurance of safety and security.
