Indonesia is an archipelagic country situated in a tropical region and is characterized by high lightning parameter values. These tropical lightning characteristics can pose problems and be detrimental to humans. Lightning detection systems serve as one of the solutions to mitigate the impacts of lightning and provide a means to study atmospheric activity. However, the lightning mapping system, which is a crucial part of the lightning detection system, requires fast computation time and high accuracy. This article proposes a 3-dimensional lightning mapping system algorithm using the Time Difference of Arrival (TDOA) method with location error of less than 100 meters and computation time of less than 1 millisecond. By simulating this algorithm with various numbers, distances, and configurations of stations, it was found that increasing the distance between stations improves the accuracy of the lightning mapping system both vertically and horizontally. Star and circular station configurations exhibit identical characteristics in location error distribution, where the accuracy at the center point of several stations will have high vertical and horizontal location accuracy. This accuracy decreases as the points move further away from the cluster of stations. Increasing the number of stations also enhances the accuracy of the lightning mapping system both vertically and horizontally. Overall, the circular configuration demonstrates consistent performance with low vertical and horizontal location errors across various distances and numbers of stations.
