Chinastar


Zhongxing and Zhongwei (Chinastar) communications satellites were orbited by China Orient Telecommunications Satellite Company, part of the Chinese telecommunications ministry. A combination of indigenous and foreign satellites are used. Zhongxing 1 to 4 were apparently some of the earlier DFH-2 and DFH-3 satellites (although more than four reached geosynchronous orbit). Zhongxing 5 was the former Spacenet 1.

  • AS 2100 American communications satellite. Operational, first launch 1996.09.08 (GE 1). Cost per satellite $100 million for the spacecraft including ground support equipment, but not including launch costs. 3-axis stabilized. More...

Associated Launch Vehicles
  • CZ-3 Chinese orbital launch vehicle. The Long March 3 was a three-stage launch vehicle designed for delivery of satellites of 1,500 kg mass into geosynchronous transfer orbit. The first and second stages were based on the CZ-2C, and designed and manufactured by the Shanghai Academy of Spaceflight Technology. The majority of the technology and flight hardware used in the CZ-3 had been qualified and proven on the CZ-2C. The third stage, manufactured by CALT, was equipped with an LOX/LH2 cryogenic engine. Long March 3 was also capable of placing spacecraft into an elliptical or circular low earth orbit and sun synchronous orbit. More...
  • CZ-3A Chinese three-stage orbital launch vehicle. The Long March 3A, by incorporating the mature technologies of the CZ-3 and adding a more powerful cryogenic third stage and more capable control system, had a greater geosynchronous transfer orbit capability, greater flexibility for attitude control, and better adaptability to a variety of launch missions. More...
  • CZ-3B Chinese orbital launch vehicle. The Long March 3B was the most powerful Long March launch vehicle. It could inject a 5,000 kg payload into geosynchronous transfer orbit. The CZ-3B was developed on the basis of the CZ-3A, but had enlarged propellant tanks, larger fairing, and four boosters strapped onto the core stage. The CZ-3B boosters were identical to those of the CZ-3A. More...
