Design and Implementation of Unattended Remote Sensing Satellite Receiving Station

文章针对无人值守遥感卫星接收站的特点及任务要求,采用任务流程调度引擎,实现了遥感卫星接收站的自动化运行调度、远程自动测试及标校;采用RMI远程访问技术,实现了客户端与服务端之间的信息交互、软件远程管理和升级及远程监控管理;对薄弱环节进行冗余设计,以提高可靠性和使用效能。设计的无人值守遥感卫星接收站已用于高分专项北极接收站,该站投入运行后工作稳定,接收成功率达99.91%。

According to the characteristics and mission requirements of unmanned remote sensing satellite receiving station,the automatic operation scheduling, remote automatic testing and calibration of remote sensing satellite receiving station are realized by using the task flow dispatching engine. Using RMI remote access technology, information interaction between client and server, software remote management and upgrade, and remote monitoring management are realized. Redundancy design of weak links is done to improve reliability and use efficiency. The designed unmanned remote sensing satellite receiving station has been used in Arctic receiving station. After the station is put into operation, the work is stable,and the success rate of receiving is 99. 91 %.
