“…The time history of the peaks shows that an insulator accummulates an electric charge over a period which is typically a few minutes. This is in agreement with measurements carried out on the SCATHA satellite (Mizera et al, 1980). The following conclusions can be drawn from these observations: (a) Differential charging caused by secondary emission is important for insulated shadowed surfaces and during eclipses.…”

This paper gives an overview of electrostatic charging which occurs on spacecraft in different plasma environments. Particular emphasis is given to differential charging between sunlit and shadowed insulated surfaces, a phenomenon which is often observed in the geostationary orbit. It can generate potential differences of several kilovolts between adjacent surfaces. This can lead to discharges and serious spacecraft anomalies such as spurious telecommands caused by voltage and current transients on cable harnesses. Experience with the GEOS and ISEE satellites has demonstrated that differential charging can be avoided by making outer surface elements conductive and connecting them to a common ground.

“…The differential potentials that develop between the satellite's surface materials and the grounded structure are complex, in fact, more complex than even these figures indicate. 9 ' 1 ' The hazards caused by spacecraft charging result from complex interactions between the space environment and the materials and ESD and electronics on a spacecraft.…”

“…Previously, initial charging results from a brief acquisition on April 24, 1979 were presented by Mizera et al 7 That event was characterized by an intense plasma injection encountered by the P78-2 satellite just prior to entering the Earth's eclipse near local midnight. P.P.…”

Electrical charging of common spacecraft materials flown on a high-altitude satellite are measured by the Satellite Surface Potential Monitor experiment and the data obtained are used as a framework for future modeling of spacecraft charging. Results from two magnetically disturbed times were chosen; one when the USAF P78-2 satellite was in eclipse on March 28, 1979 and the other which occurred in sunlight on April 24, 1979. On both days, the spacecraft charged negatively in the Earth's shadow to greater than -5 kV. From the results of these data, the location of various insulating materials, as well as their physical properties, must be considered if the details of spacecraft charging are to be understood.
