Tokyo, April 15, 2026 — NTT, Inc. and JAXA have begun on-orbit demonstration of advanced satellite communication and sensing technologies using a low Earth orbit (LEO) satellite.
The initiative utilizes the RAISE-4 satellite, launched in December 2025, equipped with a MIMO-based IoT transmission system designed to enable high-capacity satellite communications and ultra-wide-area sensing. Following successful initial testing, steady-state operations have commenced, with early results confirming that MIMO signal processing is functioning as expected.
Over the next year, the partners will conduct further experiments to validate the technology, which is expected to enhance transmission speeds, support a larger number of connected devices, and enable IoT and sensing services in remote areas without terrestrial infrastructure, such as oceans and mountainous regions.
The project is part of broader efforts to develop next-generation space-based communication networks, with potential applications in environmental monitoring, disaster prediction, and global connectivity.
