Design of real time scale acquisition for lightning localizer

The research of lightning location technology is very important to prevent and mitigate the influence of lightning on the ground, and the real-time timescale acquisition is the key factor of the technology.In this paper, GPS navigation module is used to generate accurate real-time time scales in programmable logic devices by using its second pulse as synchronous signal. In this paper, the time scales are put into the data, so that each station has its own precise time signals, which provides an important benchmark for lightning location. Through verification, when the trigger signal exceeds the threshold, real-time lightning data can be collected in microsecond, which provides important data support for lightning location.
