The increasing complexity and sophistication of synchronous orbit satellites has resulted in a corresponding increase in their susceptibility to anomalous behavior and disruption. Many of these problems can be attributed to the buildup of large potentials on various surfaces of the satellites in response to the ambient space plasma. Such large potentials (as great as -20,000 V relative to the ambient plasma) can produce anomalies and disruptions by causing arcing between the surfaces. In this report, the question of the time rate of change of satellite potential is studied. Theory and observations are reviewed to give estimates of the time rate of change in potentials encountered at synchronous orbit. A clear need for future study is indicated. Plans for instrumentation being developed at AFGL to study the area are discussed. (Author).

Rapid variations in spacecraft potential are observed on entry and exit from the earth's shadow. Generalized equations, based on elementary plasma probe theory, are developed which make quantitative estimates of these potentials as a function of satellite position in the earth's penumbra, and are compared with data from the ATS-5 and ATS-6 geosynchronous satellites. The agreement between the observations and the predictions results from the approximate constancy of the ratio of the ambient ion to electron current during injection events. Due to the significant size and shape differences of the ATS-5 and ATS-6 satellites, the results are applicable in many space physics situations such as estimating the effects of electron beams on satellite potential and of spacecraft charging on very large space structures.
