China's Chang Zheng 3B/E launches ChinaSat 6D
(17 Apr 2022) Rocket: Chang Zjeng 3B/E; Payload: Chinasat 6D (Zhongxing 6D); Date: 15 April 2022, 1205 UTC; Launch site: Xichang Satellite Launch Center, China.
The ChinaSat 6D satellite, also known as Zhongxing 6D, was deployed into orbit by the China Academy of Launch Vehicle Technology (CALT). The Chang Zheng 3B/E (CZ-3B/E) is the most powerful of the Chang Zheng 3 series of rockets that China uses for most of its geostationary satellite launches.
ChinaSat 6D was built by the state-owned China Academy of Space Technology (CAST) and will be operated by China SatCom. Equipped with 25 C-band transponders, the satellite will provide users in China with high-bit rate uplink and downlink for radio and TV stations from its station at a longitude of 125 degrees East.
The satellite is powered by two large solar arrays which charge onboard batteries. It is expected to operate for at least 15 years.
ChinaSat 6D will replace the ChinaSat 6A satellite, which was launched in September 2010 and was formerly known as SinoSat-6. ChinaSat 6A had been expected to remain in service until 2025; however, a fault with its helium pressurisation system has shortened its operational life and required that a replacement be launched sooner than had been planned.
