(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、通信广播卫星。全面推进固定通信、移动通信、数据中继卫星系统建设。“亚太”“中星”等系列通信卫星成功发射,固定业务卫星通信保障体系基本建成,覆盖中国国土及全球重点地区。首颗移动通信卫星“天通一号”成功发射。建成由三颗“天链一号”卫星组成的第一代数据中继卫星系统。星地激光链路高速通信试验取得圆满成功。“东方红五号”超大型通信卫星平台研制进展顺利。

(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、导航卫星。北斗二号系统全面建成,完成14颗北斗导航卫星发射组网,正式向亚太地区用户提供定位、测速、授时、广域差分和短报文通信服务。北斗全球系统建设正在顺利推进。

(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、新技术试验卫星。成功发射“实践九号”系列卫星等技术试验卫星,为新技术验证提供了重要手段。

(4) New technological test satellites. China has launched the Shijian-9 satellite series for technological experiments, providing an important way to test new technologies.

(三)载人航天

Manned spaceflight

2012年6月和2013年6月,“神舟九号”和“神舟十号”载人飞船先后成功发射,与“天宫一号”目标飞行器分别实施自动和手控交会对接,标志着中国全面突破了空间交会对接技术,载人天地往返运输系统首次应用性飞行取得圆满成功。2016年9月和10月,“天宫二号”空间实验室和“神舟十一号”载人飞船先后成功发射,形成组合体并稳定运行,开展了较大规模的空间科学实验与技术试验,突破掌握了航天员中期驻留、地面长时间任务支持和保障等技术。目前,中国已突破掌握载人天地往返、空间出舱、空间交会对接、组合体运行、航天员中期驻留等载人航天领域重大技术。

In June 2012 and June 2013, the Shenzhou-9 and Shenzhou-10 manned spacecraft were launched to dock with the target spacecraft Tiangong-1. They used manual and automatic operations respectively, symbolizing breakthroughs for China in spacecraft rendezvous and docking technology and full success in its first operation of a manned space transportation system. In September and October 2016, the Tiangong-2 space laboratory and Shenzhou-11 manned spacecraft were launched and formed an assembly that operates steadily, with the mission of carrying out science and technology experiments in space, indicating that China has mastered technologies concerning astronauts’ mid-term stay in orbit, and long-term ground mission support. Currently, China has mastered major space technologies such as manned space transportation, space extravehicular activity, space docking, operating in assembly and astronauts’ mid-term stay in orbit.
