WSRF 2012, Dubai
LONG MARCH LAUNCHERS Chinese Long March launches have been increasing
steadily: 157 launches in total since 1970
1st 50 launches in 28 years: From Apr 24, 1970 to Mar 26, 1998;
2nd 50 launches in 9 years: From May 2, 1998 to June 7, 2007;
Latest 57 launches in 4.5 years: From July 7, 2007 to Jan 13, 2012
19 launches in 2011, second to Russia in number of launches
21 launches scheduled for 2012
Current launch capability:
GTO: 5.5 tons LEO: 9.5 tons
WSRF 2012, Dubai
IMPROVED LAUNCH OPERATIONS
Launch operations have been optimized for GTO launches from the Xichang launch site
Launch Capacity: 8~10 missions per year LV Launch Campaign Duration: 25 days Two launch campaigns can be operated in parallel for at
least 18 days. Interval between 2 launches at Xichang launch site
Shortest interval: 17 days No.2 Launch Pad: <25 days No.2 & No.3 Launch Pad: < 20 days
Launch can be performed any time of a year.

FUTURE LV DEVELOPMENT PLAN
Next generation launch vehicles LM-5, LM-6 and LM-7, using new propulsion technology, are under development.
LM-5 Launch capability LEO: 25 tons GTO: 14 tons LM -6 Launch capability SSO: 1 ton LM -7 Launch capability LEO: 13.5 tons SSO: 5.5 tons
Wenchang Satellite Launch Center, Hainan Island, is under construction.

DFH FAMILY SPACECRAFT SUMMARY First DFH-1 satellite was launched in 1970.
First GEO Communications satellite DFH-2 was launched in1984.
First operational three-axis-stabilized GEO satellite DFH-3 was launched in 1997.
First DFH-4 satellite Sinosat-2 was launched in 2006.
Now, more than 30 CAST-developed GEO satellites have been launched:
9 satellites based on DFH-2/2A bus;
20 satellites based on DFH-3 bus, with 5 sats already achieved 8 years’ designed lifetime and still in operation;
8 satellites based on DFH-4 bus;
5 CAST-developed comsats were launched in 2011. More than 20 GEO satellites will be launched based on DFH-3 and DFH-4 bus in the next few years.
WSRF 2012, Dubai
DFH COMMUNICATIONS SATELLITES DFH-4 bus is a large capacity and long lifetime communications satellite
platform, with a maximum payload power of 8 kw.
8 satellites based on DFH-4 bus have been launched, among which Venesat-1 already has over 3 years in orbit operation. More than 200 transponder years of in-orbit operation experience accumulated for DFH-4 series of spacecrafts.
9 satellites, including three commercial projects, are currently under construction, i.e. CHINASAT-11, TKSAT-1 and SINOSAT-4.

OBSERVATIONS & EXPECTATIONS
China space keeps improving products and services in response to market demand, providing reliable technical solution, schedule assurance, reasonable pricing and packaged services.
China space will continue focusing on improving product quality.
China’s space industry will keep the current momentum for rapid development in the next few years, which will bring more opportunities to underwriters.
