Wireless Antenna Detection Of Electrostatic Discharge Events, Allen Andersen, Jr Dennison

Conference Proceedings

Wireless intra-spacecraft communication technology is being developed as a weight-saving and design-simplifying measure for signal transfer on space missions. 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 signals that can interact with wireless antennae. These interactions present a source of signal noise. However, they may 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 …
