| GPS Timing System |
Modern data acquisition or data collection systems such NetDAS use GPS modules to time-stamp the data. The software uses the GPS time stamp to create a small header with this time stamp which is read by thedisplay and analysis software. The GPS system consists of four parts: GPS card (left photo), antenna (middle) andmounting hardware (right). A coaxial cable (not shown) connects the card to the antenna. NetDAS uses the GPS RMC and GPS PPS to create the time stamp. This GPS timing system is available from DAQ Systems asa standalone product or as part of a data acquisition system such as NetDAS or POSEIDON.
