In 2007, a joint venture China Direct Broadcast Satellite was formed to run the brand ChinaSat.

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.

[9] The first three satellites have been launched from the Xichang Satellite Launch Center using Long March-3B/G2 rockets while the fourth one has been launched from the Wenchang Space Launch Site using a Long March 7A rocket, and in particular: The shift to a different launcher for the fourth satellite capable of carrying a greater mass to the intended geosynchronous orbit could indicate the use of a bigger and heavier satellite bus, possibly an upgraded version of the previously used DFH-4 bus.

DHF-3 1 was launched on 29 November 1994 but didn't reach its intended orbit and was declared lost, while ChinaSat 6 was launched on 11 May 1997 and reached its intended orbit but experienced technical malfunctions that could reduce its operational life.

[29][30] The ChinaSat 6B (ZX 6B) satellite was manufactured by Thales Alenia Space, based on the Spacebus 4000C2 platform.

It had 38 transponders, and was used for TV transmissions and shortwave jamming across China, Southeast Asia, the Pacific and Oceania.

The broadcast was used for some shortwave radio jamming purposes in China was carried on one of the Chinasat 6B transponders.

The satellite provides commercial communications services with twenty-five C-band transponders and supports high-quality and reliable uplink and downlink transmissions of programs for the radio and TV stations and cable TV networks.

Its condition remains healthy after efforts to stabilize the satellite were successful, however its lifespan has been reduced.

ChinaSat 6D (ZX-6D) was launched on 15 April 2022 at 12:00 from the Xichang Satellite Launch Center using a Long March 3B/E ad it is intended to replace ChinaSat 6A in its shortened than envisioned life span.

It is equipped with twenty-five C-band transponders and it is positioned at the orbital slot of 130° East.

ChinaSat 7, a geosynchronous communications satellite launched in 1996, experienced third stage failure and a nearly unusable orbit.

[43] ChinaSat 9 (ZX-9) was built by Thales Alenia Space and it's based on the Spacebus 4000C2 satellite bus.

It was intended to act as a relay satellite for the 2008 Olympic Games, and to be subsequently used for general communications.

[44][45] ChinaSat 9A (ZX 9A) was initially intended to be a replacement for Sinosat's Sinosat-2 communication satellite with the name Sinosat-4, and as its predecessor it's based on the DFH-4 bus.

It was launched on 16 June 2017 at 16:12 UTC from the Xichang Satellite Launch Center using a Long March 3B/E rocket, but failed to reach the intended orbit due to an upper stage failure.

[46][47] Due to its shorter than intended lifespan a replacement based on the upgraded DHF-4E bus, named ChinaSat 9B (ZX 9B), was launched on 9 September 2021 from the Xichang Satellite Launch Center using a Long March 3B/E rocket reaching its orbit without any issues.

After its experimental phase, it was transferred to China Satcom which is currently operating it as ChinaSat 16 (ZX 16).

Although the launch was successful, the satellite would later malfunction in orbit and was later declared a total loss just after three months.
