Although the role of the environment in generating spacecraft potential variations at geosynchronous orbit is well documented, variations in the ambient environment itself have not been well-defined. Similarly, no studies of the environment have attempted an analytic formulation of the various parameters needed to model the spacecraft charging phenomenon. This paper describes the parameters needed to formulate such a model and outlines a systematic procedure for constructing a simple analytic model that includes the effects of local time and geomagnetic activity. Observational data from the ATS- 5 satellite are analyzed using this procedure to give a preliminary analytic description of the geosynchronous environment in the form of a FORTRAN program.

The definitive guide to the modern body of spacecraft charging knowledge—from first principles for the beginner to intermediate and advanced concepts The only book to blend the theoretical and practical aspects of spacecraft charging, Guide to Mitigating Spacecraft Charging Effects defines the environment that not only creates the aurora, but which also can have significant effects on spacecraft, such as disruption of science measurements and solar arrays from electrostatic discharge (ESD). It describes in detail the physics of the interaction phenomenon as well as how to construct spacecraft to enhance their survivability in the harsh environment of space. Combining the authors' extensive experience in spacecraft charging—and in their provision of design support to NASA, JPL, the commercial satellite market, and numerous other projects—this incredible book offers both a robust physics background and practical advice for neophytes in the field and experienced plasma physicists and spacecraft engineers. In addition to containing numerous equations, graphs, tables, references, and illustrations, Guide to Mitigating Spacecraft Charging Effects covers: Solar cell technology, especially higher voltage arrays, and the new design approaches that are appropriate for them Information about the space plasma environment New analytic computer codes to analyze spacecraft charging Spacecraft anomalies and failures which emphasized designs that are of greater importance than others

The ambient plasma environment at geosynchronous orbit is assumed to be represented by a two-component Maxwell-Boltzmann particle distribution. Given this, the equations for ambient electron and ion currents to the spacecraft are easily integrated. Likewise, the secondary and backscattered currents can be expressed as integrals. The potential at which the currents balance gives the potential between the spacecraft and ambient plasma. The model is compared with actual data from ATS-5 and is found to agree within plus or minus 1, 200 V over a range of 0 to minus 10,000 V. The model is readily applicable to the simple environmental model of Garrett and DeForest (1979) and can be calibrated to any given satellite. Simple algorithmic expressions are also developed for the backscattered and secondary currents as a function of temperature and potential which promise a significant decrease in computer time without a significant loss in accuracy.
