20 June 2025 year Fr. 12:37 (UTC) from the center of launch of satellites Sichan, Китай за допомогою ракети-носія «Long March 3B/E» було здійснено запуск супутника зв’язку Китаю «Chinasat 9С».
«ChinaSat 9C» — це геостаціонарний телекомунікаційний супутник Ku- та Ka-діапазонів, розроблений Китайською аерокосмічною науково-технічною корпорацією (Hull) на замовлення компанії China Satcom. Він призначений для заміни супутника «ChinaSat 9» at the orbital position of 92.2° east longitude.
Satellite «ChinaSat 9C» designed using multi-beam coating technology. At the same time, special attention is paid not only to preservation, but also to improve the national coverage beam, which was already provided by the ChinaSat satellite 9. The coverage area of the new satellite should not be inferior to the previous one, а її розширення має забезпечити посилене охоплення морських акваторій та західних регіонів країни, which is especially important for the development of communications in hard-to-reach and strategically important areas.
Chinese Aerospace Scientific and Technical Corporation (Hull) is the Chinese Space Program Main Contractor. It is a state and has a number of subordinate organizations, which project, develop and produce a number of spacecraft, launch vehicles, strategic and tactical rocket systems, land equipment.
«Long March 3B” is a powerful Chinese three-stage launch vehicle with four lateral liquid-fuel boosters. It is the heaviest representative of the rocket family Long March 3 and is mainly intended for launching communication satellites into geostationary orbits.
IN 2007 year, an improved version was presented — "Long March 3B/E», which has an increased payload capacity for launching the payload into geostationary orbits. Her first flight took place 13 May 2007 year, during which the Nigerian telecommunications satellite NigComSat-1 was successfully launched. Among the rocket's notable achievements is the launch of China's first-ever lunar lander, Chang'e 3 and Yutu's moon rover 2013 year.
