Shiyan


Chinese civilian surveillance satellite. 2 launches, 2004.04.18 (Tansuo 1) to 2008.11.05 (Shiyan Weixing 3). The first 'Experiment Satellite', with a mass of 204 kg, was China's first transmission-type small satellite capable of stereo mapping.

It was jointly designed by the Harbin Polytechnic University, Chinese Research Institute of Space Technology, Changchun Photomechanical Institute of the Chinese Academy of Sciences (CAS) and Xian Surveys and Designs Institute. It seems to have been derived from the Tansuo-1 (Exploration-1) high-resolution imaging microsatellite, developed by the Harbin Institute of Technology (HIT) and announced in early June 2000. This satellite was to have been launched in 2001, but never appeared. Tansuo-1 was a 150-kg microsatellite with a 10-meter stereo resolution camera. It was developed in collaboration with the European Astrium Corporation.

The satellite was, officially, mainly to be used to carry out a photographic survey of China's land resources, monitor its geographical environment and conduct scientific mapping research. It was to be handed over to the Satellite Remote-Sensing Ground Station of CAS following the on-orbit testing.

  • CZ China's first ICBM, the DF-5, first flew in 1971. It was a two-stage storable-propellant rocket in the same class as the American Titan, the Russian R-36, or the European Ariane. The DF-5 spawned a long series of Long March ("Chang Zheng") CZ-2, CZ-3, and CZ-4 launch vehicles. These used cryogenic engines for upper stages and liquid-propellant strap-on motors to create a family of 12 Long-March rocket configurations capable of placing up to 9,200 kg into orbit. In 2000 China began development of a new generation of expendable launch vehicles using non-toxic, high-performance propellants with supposedly lower operating costs. However these encountered development delays, and it seemed the reliable Long March series of rockets would continue in operational use for nearly fifty years before being replaced. More...

  • CZ-2C Chinese orbital launch vehicle. The CZ-2C was the definitive low earth orbit launch vehicle derived from DF-5 ICBM. It became the basis for an entire family of subsequent Long March vehicles. Many adaptive modifications were made to the configuration of the CZ-2A to handle a variety of new satellites and upper stages. The CZ-2C had improved technical performance and payload capacity compared to the CZ-2A, with later versions having a payload capability of 2,800 kg into a 200 km circular orbit. More...
  • CZ-2D Chinese orbital launch vehicle. The Long March 2D was a two-stage launch vehicle with storable propellants, suitable for launching a variety of low earth orbit satellites. Developed and manufactured by the Shanghai Academy of Spaceflight Technology, the CZ-2D had a typical payload capability of 3,500kg in a 200 km circular orbit. Its first stage was identical to that of the CZ-4. The second stage was essentially the same as that of the CZ-4, except for an improved vehicle equipment bay. More...
