摘要
GPS&IRIG-B码时间系统把GPS卫星信号和现代化靶场间通用的IRIG-B(Inter-RangeInstrumentationGroup,靶场仪器组B型格式)串行时间码封装于一体,通过PCI总线与计算机联系起来,提供高精度的定时服务。此接收板具有集成度高、体积小、工作稳定的特点。该文详细阐述了IRIG-B码标准,并从工程实施的角度出发,说明此时间系统的软硬件设计过程。
The GPS & IRIG-B code time system encapsulates the GPS satellite signal and modernized IRIG-B (B type format of Inter-Range Instrumentation Group) serial time code and connect them to the computer through a PCI bus, thus offering accurate timing service. This receiving card has the virtues of high integration, small size and stable output. This paper introduces the standard IRIG-B code and discusses the software and hardware design of this time system from the viewpoint of engineering implementation.
