Sinosat 2, 4 (Xinnuo 2, 4) / ZX 9A (ChinaSat 9A)

Sinosat 2 [CAST]

In response to the growing demand of the regional market, Sinosat is adding a new member, Xinnuo 2 (Sinosat 2), to its fleet of satellites. With 24 Ku-band transponders on board, Sinosat-2 will be the first spacecraft based on the chinese high power satellite platform, known as DFH-4.

Being the major satellite platform of new generation, DFH-4 is of high power, high quality and high reliability. Based on the mature DFH-3 platform, DFH-4 is designed and developed to meet similar performance as that of A2100AX, FS1300 and SB3000B3. To ensure the time schedule and performance requirements, the telecommunication payload of the Sinosat-2 payload will be imported from Alcatel.

Sinosat-2 was to be delivered in the first half of 2005. Launched in October 2006, the lifetime of Sinosat-2 was to be 15 years. The new satellite will serve the need for TV broadcasting, DirectPC and broadband multimedia systems in China as well as the neighboring areas

Reportedly the satellite failed to deploy its solar arays after reaching geostationary orbit.

A replacement satellite called Xinnuo 4 (Sinosat 4) was due to be launched in late 2008, but has been delayed to 2011. In 2010, the satellite was taken over by China Satcom and renamed ZX 9A (ChinaSat 9A). Reportedly parts produced for ZX 9A have been used for other satellites, so the launch date reamins uncertain.
