Aerospace EMI/EMC Compliance

A defense prime contractor developing high-altitude platforms needed to demonstrate EMI/EMC compliance across multiple standards to obtain flight clearance. The platforms carried complex antenna systems with potential for interference between colocated transmitters and receivers, and compliance documentation was required for both domestic and international operations.

The core challenge was performing comprehensive electromagnetic interference analysis for platforms with dozens of antenna systems operating across a wide frequency range. Manual analysis was impractical given the number of potential interference paths, and compliance documentation needed to satisfy multiple regulatory frameworks simultaneously.

Without demonstrated compliance, the platforms would be grounded indefinitely, blocking operational deployment and program milestones.

The engagement delivered comprehensive EMI/EMC analysis including automated EMIT cosite modeling, interference path analysis, and compliance documentation formatted for certification authority submission.

The engagement delivered comprehensive EMI/EMC compliance packages demonstrating that platform antenna systems meet all applicable standards. The automated EMIT analysis identified and characterized all potential interference paths, with detailed link budget analyses for scenarios requiring mitigation.

The platform obtained both domestic and international flight clearances, enabling operational deployment. The automated analysis approach has been retained for ongoing configuration management, allowing rapid assessment of proposed equipment changes.
