It has 6 S and Ku band channels with repeaters manufactured by Thales Alenia Space and other equipment manufactured by Sumitomo. The Ku band antenna operates at up to 150 Mbit/s and the S band antenna at up to 5 Mbit/s. The satellite also relays COSPAS/SARSAT signals and Planet-S System data.〔〔〔〔〔〔 The satellite is designed to relay data from the ISS, satellites in low earth orbit and rocket launch vehicles.〔 Luch 5A is located at 167° E. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Luch 5A」の詳細全文を読む スポンサード リンク
