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

Journal Articles

Wireless intraspacecraft communication technology is being developed for signal transfer on space missions to save weight and simplify the design. One consideration for this new technology is its interaction with space environmentinduced electrostatic discharges (ESDs). The short time scales of spacecraft ESD events result 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 …

Spacecraft charging is one of the leading causes of space environment induced anomalies [1]. Spacecraft charging occurs when an electric charge builds up on a spacecraft; one way for the charge to accumulate is from natural space plasma [1]. The charge can lead to many different problems, including electrostatic discharge (ESD). Insulating materials such as highly disordered polymers do not allow charge to move freely; this can result in areas of localized charge to build up creating differing electric potentials [2]. Once the difference in potentials is great enough, electrostatic discharge occurs causing irreversible damages to the insulating polymers.
