5G実験運用

5G Experimental Operation

2026-03-13

3月13日，5G実験運用を実施しました．本実験では，膜面上に搭載された送信機と衛星本体との間で通信を行いました．
本実験の成果は，展開膜の非平面形状を補償するビームフォーミング技術を用いた，大口径・軽量・高収納率な展開型アレーアンテナの実現に向けた第一歩となります．
5G系より一言：打ち上げ後も緊張の連続でしたが，何年もかけて開発してきたアンテナが無事に動作し，東京科学大メンバー一同ほっとしています！（駒場）
引き続き，HELIOS-Rプロジェクトをよろしくお願いいたします．

On March 13, we conducted the 5G experimental operation. In this experiment, communication was established between the transmitter mounted on the membrane and the receiver installed on the satellite body.
This experiment is a first step toward realizing large-aperture, lightweight, and highly stowable deployable array antennas that use beamforming technology to compensate for the non-planar shape of deployed membranes.
A comment from the 5G team: Even after launch, it was a tense and exciting time for us. We're delighted to see that the antenna we spent years developing is operating successfully, and the entire Institute of Science Tokyo team is greatly relieved! (Komaba)
Thank you for your continued support of the HELIOS-R project.
