II. Major Developments Since 2011
Since 2011 China's space industry has witnessed rapid progress manifested by markedly enhanced capacity in independent innovation and access to outer space, constant improvement in space infrastructure, smooth implementation of major projects such as manned spaceflight, lunar exploration, the Beidou Navigation System and high-resolution earth observation system, and substantial achievements in space science, technology and applications.
1.Space transportation system
From 2011 to November 2016 the Long March carrier rocket series completed 86 launch missions, sending over 100 spacecraft into target orbit with a success rate of 97.67 percent, indication of increasing effectiveness and high-density launching capability of carrier rockets. The Long March 5 (CZ-5), China's newest generation of carrier rockets with a maximum carrying capacity, made its maiden flight, and increased the diameter of liquid fuel rocket from 3.35 m to 5 m, with a maximum payload capacity of about 25 tons to low earth orbit and about 14 tons to geostationary transfer orbit, significantly improving the carrying capacity of the Long March rocket family and becoming a symbol of the upgrading of China's carrier rockets. The development of the 120-ton liquid oxygen and kerosene engine was test fired, which powered Long March 6 and Long March 7 on their maiden flights. The Long March 11, a solid-fuel carrier rocket, also made a successful maiden launch, further enriching the Long March rocket family.
2. Man-made satellites
(1) Earth observation satellites. The function of the Fengyun (Wind and Cloud), Haiyang (Ocean), Ziyuan (Resources), Gaofen (High Resolution), Yaogan (Remote-Sensing) and Tianhui (Space Mapping) satellite series and constellation of small satellites for environment and disaster monitoring and forecasting has been improved. The Fengyun polar orbit meteorological satellite has succeeded in networking observation by morning and afternoon satellites, while its geostationary earth orbit (GEO) meteorological satellite has formed a business mode of "multi-satellites in orbit, coordinated operation, mutual backup and encryption at the appropriate time." The Haiyang-2 satellite is capable of all-weather, full-time and high-accuracy observation of marine dynamic parameters such as sea height, sea wave and sea surface wind. The Ziyuan-1 02C satellite was launched, the Ziyuan-3 01 and 02 stereo mapping satellites have achieved double star networking and operating. The China High-resolution Earth Observation System program has been fully implemented; the Gaofen-2 is capable of sub-meter optical remote-sensing observation, the Gaofen-3 has a Synthetic Aperture Radar (SAR) imaging instrument that is accurate to one meter and the Gaofen-4 is China's first geosynchronous orbit high-resolution earth observation satellite. Satellite C of the environment and disaster monitoring and forecasting small satellite constellation has been put into use. The successful launching of the Kuaizhou-1 and Kuaizhou-2, which adopted integrated design of the satellite and the launch vehicle, has improved China's emergency response capability in space. The Jilin-1, a high-resolution remote-sensing satellite for commercial use has been launched and put into service.
(2) Communications and broadcasting satellites. China has comprehensively advanced the construction of fixed, mobile and data relay satellite systems. The successful launch of communications satellites such as Yatai and Zhongxing represented the completion of a fixed communications satellite support system whose communications services cover all of China's territory as well as major areas of the world. The Tiantong-1, China's first mobile communications satellite, has been successfully launched. The first-generation data relay satellite system composed of three Tianlian-1 satellites has been completed, and high-speed communication test of satellite-ground laser link has been crowned with success. In addition, the development of the DFH-5 super communications satellite platform is going smoothly.
(3) Navigation and positioning satellites. The Beidou Navigation Satellite System (Beidou-2) has been completed, with the networking of 14 Beidou navigation satellites, officially offering positioning, velocity measurement, timing, wide area difference and short-message communication service to customers in the Asia-Pacific region. Beidou's global satellite navigation system is undergoing smooth construction.
(4) New technological test satellites. China has launched the Shijian-9 satellite series for technological experiments, providing an important way to test new technologies.
