“…Such location methods are obviously similar to standard GPS applications, which use similar GHz frequency signals [D]. We note that similar methods have been developed for detecting discharges in terrestrial applications, such as high voltage DC power transmission or consumer electronics [5][6][7][8]. However, in this paper we demonstrate that the methods are still effective when using cost-effective, standard, off-the-shelf Wi-Fi antennas rather than antennas that are specifically designed for identifying ESD.…”

Wireless intra-spacecraft communication technology is being developed for signal transfer on space missions to save weight and simplify design. One consideration for this new technology is its interaction with space environment-induced electrostatic discharges (ESD). The short time scales of spacecraft ESD events results in broad frequency band signals that can interact with high frequency wireless antennas. These interactions present a source of signal noise. However, they also present a possibility of in-flight wireless ESD monitoring. We present laboratory measurements of arcing on common spacecraft insulators using commercially available single band 2.4 GHz and dual band 2.4/5.8 GHz Wi-Fi antennas. These wireless detections are shown to coincide with direct simultaneous measurements of discharge event currents. The amplitudes of the wireless signals are shown to provide a measure of the relative magnitude of the arcs, although the narrow frequency ranges of Wi-Fi antennas make absolute measures of the discharge intensity impractical. The wireless signals are shown to provide very accurate nsec timing of ESD events, which presents the potential of identifying arc location on a spacecraft with the use of time-offlight detection from multiple antennas.
