（二）人造地球卫星

    重点构建由对地观测、通信广播、导航定位等卫星组成的空间基础设施框架，初步形成长期、连续、稳定的业务服务能力。发展新型科学卫星与技术试验卫星。

    1.对地观测卫星。完善已有“风云”、“海洋”、“资源”等卫星系列和“环境与灾害监测预报小卫星星座”，研制发射新一代地球静止轨道气象卫星、立体测绘卫星、环境与灾害监测雷达卫星、电磁监测试验卫星等新型对地观测卫星，开展干涉合成孔径雷达、重力场测量等卫星的关键技术攻关。全面实施高分辨率对地观测系统重大科技专项。基本形成全天候、全天时、多谱段、不同分辨率、稳定运行的对地观测体系。

2. Man-made Earth Satellites

China will build a space infrastructure frame composed of Earth observation satellites, communications and broadcasting satellites, plus navigation and positioning satellites, and will develop a preliminary long-term, sustained and stable service capability. China will develop new types of scientific satellites and technological test satellites.

1) Earth observation satellites

China will improve its present meteorological, oceanic, and resource satellite series and its small satellites constellation for environmental and disaster monitoring and forecasting. It aims at developing and launching new-generation GEO meteorological satellites, stereo mapping satellites, radar satellites for environment and disaster monitoring, electromagnetic monitoring test satellites, and other new-type Earth observation satellites. It will work to make breakthroughs in key technologies for interferometric synthetic-aperture radar and gravitational field measurement satellites. It will initiate a high-resolution Earth observation system as an important scientific and technological project and establish on the whole a stable all-weather, 24-hour, multi-spectral, various-resolution Earth observation system.

    2.通信广播卫星。完善固定通信业务卫星、电视广播业务卫星以及数据中继卫星，发展移动通信业务卫星，研制更大容量、更大功率的新一代地球静止轨道通信广播卫星平台。

    3.导航定位卫星。按照从试验系统，到区域系统，再到全球系统的“三步走”发展思路，继续构建中国“北斗”卫星导航系统。2012年前，建成“北斗”卫星导航区域系统，具备提供覆盖亚太地区的导航定位、授时和短报文通信服务的能力；2020年左右，建成由5颗地球静止轨道卫星和30颗非地球静止轨道卫星组成的覆盖全球的“北斗”卫星导航系统。

2) Communications and broadcasting satellites

China will improve satellites for fixed communications services, television and radio service satellites and data relay satellites; develop satellites for mobile communication service; and develop a platform of higher capacity and higher power for new-generation GEO communications and broadcasting satellites. 

3) Navigation and positioning satellites

Based on "three-step" development plan - from experimental system to regional system and then to global system, China will continue building its Beidou satellite navigation system, implementing a regional Beidou satellite navigation system before 2012, whose navigation and positioning, timing and short-message services will cover the Asia-Pacific region. China aims at completing the global Beidou satellite navigation system by 2020, comprising five GEO satellites and 30 non-GEO satellites.
