SIRF. The Operating Center. Data coming from each sensor are received and elaborated by the central analyzer, which calculate, in a few seconds, the impact geographic coordinates, the time of impact and the electric parameters of each lightning event (current amplitude, polarity, number of strokes). Calculated data are thus ready to be sent to customers or to be saved into the central database. From this database all the information can be extracted at any time and in any format (statistics, maps, tables, ASCII file, and so on) and, in needed, provided at any customer.
