In response to the growing demand of the regional market, SINOSAT is adding a new member, 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 is expected to be delivered in the first half of 2005. Scheduled to be launched in 2005, the lifetime of SINOSAT-2 will be 15 years. The new satellite will serve the need for TV broadcasting, DirecPC and broadband multimedia systems in China as well as the neighboring areas
Sinosat Comms. Co. Ltd of Beijing. First DFH-4. Chinese DBS satellite for Ku-band TV and broadband at 92.2E. Mass up to 5300 kg. Box + 2 panels. Launch by CZ-3B. Span would have been around 30m?
After orbit insertion, the satellite suffered a comprehensive failure, with the solar panels failing to deploy. The satellite was able to test out internal systems using the limited power available from the folded-up exterior panels. It was retired in 2008 and the orbit was raised in two stages in mid and late 2009.
