The Achievements and Economic Analysis of Chinese Application Satellites

本文综述了我国应用卫星在国土普查、资源探测、通信、广播、气象等方面的利用情况;对我国“七五”计划期间成功发射的11颗卫星的经济效益进行了初步分析;展望了今后十年各部门对应用卫星提出的新需求;最后讨论了我国应用卫星进一步发展所存在的问题。

By the end of 1990, China has launched 30 China-made earth satellites, 19 of them are appilication ones which include recoverable remote sensing satellites, telecommunication satellites and meteorological satellites. The related departments of the state use the data from China's recoverable remote sensing satellites to perform territory survey, geological survey, mineral prospecting, mapping, investigation of forests and grasslands, environment monitoring and protection, earthquake prediction, sea route construction, highway construction, railway and bridge construction, water conservancy development, city planning and scientific research of microgravity, etc.. The related de-partments use the data from China's meteorological satellites for weather forecast, etc.. The related departments have developed various projects, via the telecommunication sat-ellites launched by China, such as communication, broadcast, television relay, facsimile for pictrues and writings, TV education and finance, etc.. In this article, preliminary ana-lysis of the economic benefits of the 11 satellites successfully launched by China during the Seventh Five Year Plan are also revealed here. Finally, it describes the new require-ments for application satellites for next ten years from different departments.
