Electronic data acquisition, control, and diagnostic hardware are an integral part of an electromagnetic launcher system. Electromagnetic and electrostatic shielding, in addition to proper grounding, can extend the hardware's useful life, improve the signal-to-noise ratio, and reduce the threat of electrical shock. The concepts of signal shielding, single point star grounding, maintenance of the ground with the ground monitor system (GMS), and the minimum recommended practices that have proven effective in electrical noise and shock hazard abatement are discussed. >
