In order to solve the problem of interference between the sub-systems of the satellite to ensure the electromagnetic compatibility between the equipments, sub-systems and the whole system of satellite, the causes for electromagnetic interference, the approach of electromagnetic interferential coupling, the electromagnetic compatibility design and the material selection being taken to minimize the conductive interference and the interference of space lay are discussed. The electromagnetic compatibility design for the whole circuit of small satellites is discussed. The measurement result indicates that the design is reasonable, the running is proper and the design requisition is attained.
