#18074–Feasibility of using GPS to synchronize Data Acquisition Systems (DAQ) for Acoustic and Vibration measurements.

This paper investigates the use of GPS timing signals as a method to synchronize measurements across multiple data acquisition systems. Many applications require synchronization of measurements from channels distributed across multiple acquisition systems. Multiple systems are often needed for large channel counts, to simplify sensor cabling, or when measurement points are distributed physically. When systems can be connected using Ethernet, Precision Timing Protocol (PTP) provides excellent synchronization. However, when Ethernet is not a viable option due to physical distance, mobile measurement points, or other barriers, GPS sources can be used to provide precision timing for measurements.
