Spacecraft Design Guidelines
In Section 3.1 we describe processes involved in immunizing a spacecraft against spacecraft charging problems. Design guidelines are listed in Section 3.2. If the reader wishes to make a requirements document, the basic requirements include:
Sections 3.2.1 (General ESD Design Guidelines), 3.2.2 (Surface ESD Design Guidelines, Excluding Solar Arrays), 3.2.3 (Internal ESD Design Guidelines), 3.2.4 (Solar Array ESD Design Guidelines), and 3.2.5 (Special Situations ESD Design Guidelines) can be used as aids.
The system developer should demonstrate through design practices, test, and analysis that spacecraft charging effects will not cause a failure to meet mission objectives. We discuss those processes briefly in this section.
The classic approach to avoiding or eliminating electromagnetic problems is to look at the source of the problem, the victim, and the coupling between them. In the case of space charging, excess electrons deposit on surface or external spacecraft areas or penetrate directly to victim circuit areas, the charge being buried in a circuit board immediately adjacent to the victim. As a result, the three elements (source, coupling, and ...
