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.通信廣播衛(wèi)星。完善固定通信業(yè)務(wù)衛(wèi)星、電視廣播業(yè)務(wù)衛(wèi)星以及數(shù)據(jù)中繼衛(wèi)星，發(fā)展移動(dòng)通信業(yè)務(wù)衛(wèi)星，研制更大容量、更大功率的新一代地球靜止軌道通信廣播衛(wèi)星平臺(tái)。
3.導(dǎo)航定位衛(wèi)星。按照從試驗(yàn)系統(tǒng)，到區(qū)域系統(tǒng)，再到全球系統(tǒng)的“三步走”發(fā)展思路，繼續(xù)構(gòu)建中國(guó)“北斗”衛(wèi)星導(dǎo)航系統(tǒng)。2012年前，建成“北斗”衛(wèi)星導(dǎo)航區(qū)域系統(tǒng)，具備提供覆蓋亞太地區(qū)的導(dǎo)航定位、授時(shí)和短報(bào)文通信服務(wù)的能力；2020年左右，建成由5顆地球靜止軌道衛(wèi)星和30顆非地球靜止軌道衛(wèi)星組成的覆蓋全球的“北斗”衛(wèi)星導(dǎo)航系統(tǒng)。
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.
