精密单点定位(Precise Point Positioning, PPP)技术由美国喷气推进实验室( JPL ) 的Zumberge 于1997年提出。20世纪90年代末,由于全球GPS跟踪站的数量急剧上升,全球GPS数据处理工作量不断增加,计算时间呈指数上升。为了解决这个问题,作为国际GPS服务组( IGS)的一个数据分析中心, JPL提出了这一方法,用于非核心GPS站的数据处理。
Precise Point Positioning (Precise Point Positioning, PPP) technology by the U.S. Jet Propulsion Laboratory (JPL) of the Zumberge made in 1997. 90' s at the end of the 20th century, the global GPS tracking sharp rise in the number of stations, the global GPS data processing ever-increasing workload, an exponential increase in computing time. To solve this problem, as the International GPS Service (IGS), a Data Analysis Center, JPL proposed this approach for non-core data-processing of GPS stations. (2009-07-20, WORD, 21KB, 下载56次)

中国联通GSM直放站系统统一监控管理协议规范1.0
本技术规范规定中国联通GSM直放站网络管理协议和直放站设备的网管接口技术要求。
直放站网管系统一般由监控中心、通信信道和直放站三部分组成。监控中心的主要职能是对众多厂家提供的多类型、多数量的直放站进行“集中控制，统一监管”。监控中心对直放站的操作主要包括参数设置、数据查询、告警处理三种主业务；直放站作为被监管对象，在被动应答来自监控中心的命令外还必须将当前故障信息以告警命令的形式主动上报给监控中心。监控中心和直放站的通信方式可以是RS232串口直连、有线MODEM拨号和GSM短信方式等
