“…While Ferguson [31] showed that, for one type of solar cell array in low Earth orbit (LEO), the arcing voltage threshold was independent of whether the tests were performed on the ground or in space, no such studies have been done for GEO satellites, and other studies, such as that done by Wright et al [32], have indicated that end-of-life thresholds may be different than those measured at beginning of life, due to materials aging effects. The only way to be sure of arc thresholds for a given satellite on orbit is to have onboard voltage and arc-pulse monitors.…”

Recently, the debate on what is the best daytime Geosynchronous Earth Orbit spacecraft charging index has been reopened. In this paper, the conclusions of one of the recent papers on the subject are verified by comparing Nascap-2k results with charging and fluxes measured on the Spacecraft Charging at the High Altitudes, Intelsat, Defense Satellite Communications System, and Los Alamos National Laboratory Geosynchronous Earth Orbit satellites. In addition, a refined measure of charging is presented as the total thermal electron flux above a certain minimum energy that is well above the second crossover point in secondary electron emission. The use of this type of index is justified by correlations between Nascap-2k simulation results and total fluxes above a range of energies. The best minimum energy to use is determined for spacecraft of different design and surface materials. Finally, the optimum Geosynchronous Earth Orbit daytime spacecraft charging index is obtained, and its use for predicting and resolving spacecraft anomalies in real time is justified.

“…Other important strategies are to ensure that any potential problems such as floating conductors and dielectrics have either appropriate bleed paths to reduce charge build up or filters to minimize the size and passage of any resultant ESD pulses. Finally, lab testing is sometimes carried out to investigate the susceptibility of hardware to ESD, and the impact should occur [ Likar et al ., ; Wright et al ., ; Hoang et al ., ; Wong et al ., , Likar et al ., ].…”

This paper describes space weather impacts to the satellite infrastructure as perceived by satellite industry stakeholders. The information was gathered through in‐person and remote meetings with both satellite operators and manufacturers. The paper describes current impacts, industry processes for managing and mitigating impacts, costs, and industry needs and requirements. Lastly, we suggest potential improvements and solutions to problem areas based on our observation of the industry processes including (1) improved tools for quick anomaly attribution, (2) training, and (3) coordinated information sharing.
