Space and Satellite EMC
Space and satellite electromagnetic compatibility presents unique challenges that extend far beyond terrestrial EMC concerns. Spacecraft operate in an environment where the electromagnetic spectrum is both a critical resource and a source of potentially catastrophic interference. From the intense radiation of solar events to the delicate balance of onboard systems communicating with ground stations millions of kilometers away, space EMC engineering requires meticulous attention to every aspect of electromagnetic design.
The space environment itself introduces phenomena rarely encountered on Earth: charged particle bombardment, plasma interactions, electrostatic discharge events in vacuum, and the complete absence of atmospheric shielding. These factors, combined with the impossibility of on-orbit repairs and the extreme cost of mission failures, make space EMC one of the most demanding disciplines in electronics engineering. Success requires integrating EMC considerations from the earliest conceptual design phases through launch, deployment, and operational lifetime.
