Electromagnetic compatibility (EMC) is an important subject in electronics and communications. The proper performance of a system is very much dependent on meeting EMC requirements. This is more important in space systems. In this paper, the first part of a two-part text about EMC in space systems is presented. The importance of the subject and the necessity to take the EMC considerations into account from the very beginning phases of the system design is discussed. The three main EMC subject areas: sources of noise, noise transfer paths, and immunity methods are mentioned. The most important global military and space EMC standards are presented. System level actions and design considerations are also mentioned. Theses include: grounding methods, shielding and related topics, such as shielding effectiveness, shield resonance, absorbers, EMC gaskets and issues regarding wirings, cables, and connectors.
