ABSTRACT

All spacecraft systems are required to be compatible with the electromagnetic interference expected from internal and external sources. For decades, the electromagnetic interference (EMI) and electromagnetic compability (EMC) requirements have come from MIL-STD-461. It specified the maximum emission limit of the potential culprit, and the minimum susceptibility level of the potential victim equipment. The companion MILSTD-462 defined the test methods for verifying that MIL-STD-461 requirements are met, and MIL-STD-463 defined the applicable terms and units. The first two standards are now merged into one, MIL-STD-461. For complying with the EMI/EMC requirements, the contractor of commercial and defense spacecraft is required to develop the following three documents and submit to the customer as deliverables:

1. EMC control plan containing the analysis of expected EMI in the spacecraft versus the imposed requirement, and the steps to be taken for making the two compatible.
