AbstractA field programmable gate array (FPGA) is used to decode Inter-Range Instrumentation Group (IRIG) time code for a PC-based Time-Space-Position Information (TSPI) acquisition. The FPGA architecture can latch time via an external event trigger or a programmable periodic internal event. By syncing time with an external IRIG Group Type B (IRIG-B) signal and using an 8 megahertz (MHz) internal clock, captured time has 125 nanosecond (ns) precision. A Range Instrumentation Control System (RICS) application utilizing the FPGA design to capture IRIG time is presented and test results show matching time accuracy when compared to commercial IRIG time capture hardware components.
