摘　　要：随着数据应用的发展,用户对数据传输的精确性、时效性、广域性提出了更高的要求。文章介绍了ORBCOMM、Argos、Aprize等几个国外典型数据微小卫星星座的发展情况,阐述了发展数据微小卫星系统的意义及必要性,从灾害监测、环境保护和商业应用等方面列举了系统的应用需求,分析了实时转发和储存转发两种业务发展模式,给出了系统的建设内容,包括空间段、地面段和应用段,为卫星数据采集产业的发展提供思路。With development of data applications related industries, accuracy, real-time and wide area of data transmission are higherly required. The ORBCOMM, Argos, Aprize and several oth- er data communication mierosatellite constellation systems are introduced in this paper. The sig- nificance of developing microsatellite based Data Communication System （DCS） is expounded. Application requirements such as disaster monitoring, environmental protection and commercial applications are listed. Meanwhile, the operating modes, including real-time forward and storage forward are analyzed, and the components, including satellites, earth stations and terminals, are given as a reference to satellite based data communication system development.
