Chinasat

From Wikipedia, the free encyclopedia

ChinaSat (Chinese: 中星; pinyin: Zhōngxīng) is the brand name of communications satellites operated by China Satellite Communications.

History[]

In 2007, a joint venture was formed to run the brand ChinaSat.[1][2][3] It was a joint venture of state-owned companies China Satellite Communications, and Sino Satellite Communications. The latter was controlled by China Aerospace Science and Technology Corporation (CASC). However, China Satellite Communications was changed from a direct subsidiary of the State-owned Assets Supervision and Administration Commission of the State Council (SASAC) to a direct subsidiary of CASC in 2009, the joint venture was dissolved and Sino Satellite Communications became a subsidiary of China Satellite Communications.

The brand ChinaSat was previously operated by China Telecommunications Broadcast Satellite Corporation, which was owned by China's Ministry of Posts and Telecommunications.[4] China Telecommunications Broadcast Satellite Corporation was merged with other state-owned companies to form China Satellite Communications Corporation circa 2000.[5]

Satellites formerly operated by Sino Satellite Communications and China Orient Telecommunications Satellite were renamed with ChinaSat designations following the acquisition of China Satellite Communications by CASC. ChinaStar 1 became ChinaSat 5A,[6] SinoSat 1 became ChinaSat 5B,[7] and SinoSat 3 became ChinaSat 5C.[8]

Satellites[]

ChinaSat 2A[]

ChinaSat 2A was launched in 2012.[9]

ChinaSat 5A[]

ChinaSat 5A was launched in 1998, formerly known as ChinaStar 1.[10] It was leased to China Satellite Communications's subsidiary APT Satellite Holdings and renamed to Apstar 9A on 9 January 2014.[11]

ChinaSat 5B[]

ChinaSat 5B was launched in 1998, formerly known as Sinosat 1. It was sold to in 2012.[12]

ChinaSat 5C[]

ChinaSat 5C was launched in 2007, formerly known as SinoSat 3. It was leased to Eutelsat in 2011 (as and then ).[13]

ChinaSat 5D[]

ChinaSat 5D was launched in 1996, formerly known as Apstar 1A.[14] It was placed in geosynchronous orbit at a longitude of 51.5° East circa 2009.[15] It was acquired by China Satellite Communications from subsidiary APT Satellite Holdings.

ChinaSat 5E[]

ChinaSat 5E was launched in 1994, formerly known as Apstar 1.[14] It was placed in geosynchronous orbit at a longitude of 142° East[16] and moved to 163° East circa 2012.[17] It was acquired by China Satellite Communications from subsidiary APT Satellite Holdings.

ChinaSat 6[]

ChinaSat 6 were two satellites launched in 1994 and 1997. The first satellite was lost and the second suffered from reduced life.[18]

ChinaSat 6A[]

ChinaSat 6A was launched in 2010. Formerly known as SinoSat 6.[19]

ChinaSat 6B[]

The ChinaSat 6B satellite was manufactured by Thales Alenia Space, based on the Spacebus 4000C2 platform. It has 38 transponders, and is being used for TV transmissions and shortwave jamming across China, Southeast Asia, the Pacific and Oceania. It has a planned useful life of 15 years.[20] The launch, on a Long March 3B launch vehicle, was successfully conducted on 5 July 2007. The broadcast used for some shortwave radio jamming purposes in China is carried on one of the Chinasat 6B transponders.[21]

United States ITAR restrictions prohibited the export of satellite components for satellites launched on Chinese rockets. In response, Thales Alenia built ChinaSat 6B as an ITAR-free satellite, containing no restricted U.S. satellite components.[22] However, the U.S. Department of State did not accept the ITAR-free status of these satellites and fined the U.S. company Aeroflex US$8 million for exporting satellite components. In 2013, Thales Alenia discontinued its ITAR-free satellite line.[23]

ChinaSat 8[]

ChinaSat 8 was built by Space Systems/Loral and scheduled for launch in April 1999 on a Long March 3B launch vehicle.[24] However, the U.S Department of State blocked its export to China under ITAR regulations.[25] The satellite was sold to ProtoStar in 2006.[26]
