Using GPS Receiver 1PPS Output to Verify Time Stamp Accuracy and Measure Propagation Delay
[摘要] A simple pulse overlay circuit using a logic OR gate was developed to overlay a precise leading edge 1 pulse per second time reference marker from a global positioning system receiver onto a non-return -to- zero-level pulse code modulation telemetry data stream to validate time stamp accuracy and measure propagation delay in telemetry equipment.
