Maritime & Aviation

Maritime EMC testing verifies that electronic equipment used on vessels complies with electromagnetic compatibility requirements to ensure safe and reliable operation in marine environments. Marine systems must function without causing or experiencing harmful interference, particularly in navigation, communication, and safety-critical equipment. A useful class guideline is DNV-CG-0339 which contains essential EMC requirements.

RTCA DO-160 is a widely recognized aviation standard that defines EMC test procedures for airborne equipment. It includes sections covering radiated emissions, conducted emissions, radiated susceptibility, lightning effects, power input variations, and other EMC tests.

Maritime and aviation environments present unique electromagnetic and environmental stress conditions, including high-power transmitters, lightning exposure, power quality variations, and safety-critical operational requirements. Standards for these industries are typically more stringent than general commercial EMC requirements.

Yes. We assist manufacturers in developing integrated compliance strategies that address FCC testing, maritime standards, and aviation requirements simultaneously when applicable.

Typical documentation may include:

• Test plans and procedures

• EMC test reports

• Technical construction files

• FCC filings (if applicable)

We provide structured reporting aligned with applicable standards and regulatory expectations.

Yes. We support OEMs, avionics manufacturers, marine electronics developers, defense contractors, and system integrators requiring technically rigorous EMC and FCC testing services.

Aviation EMC testing ensures that airborne and ground-based electronic systems meet electromagnetic interference (EMI) and susceptibility requirements. Testing is commonly performed to standards such as RTCA DO-160 to confirm equipment can operate safely within aircraft electrical and electromagnetic environments.

If a maritime device contains intentional or unintentional RF emitters and will be marketed in the United States, it must comply with FCC regulations in addition to any marine-specific requirements.

What types of products require maritime or aviation EMC testing?

Common products include:

• Marine navigation systems

• Shipboard communication equipment

• Radar and sonar systems

• Aircraft avionics and control systems

• Satellite communication devices

• Onboard power and control electronics

Any electronic system operating in marine or aviation environments may require EMC validation.

Early engagement during product design is strongly recommended. Pre-compliance testing can identify shielding, grounding, or filtering issues before final certification testing begins, reducing cost and schedule risk.

Failure analysis is a common part of compliance development. We work with engineering teams to identify root causes and recommend corrective design actions, followed by re-evaluation as needed.

GME Electromagnetics provides technically precise testing, detailed standards interpretation, and direct collaboration with engineering teams. Our focus is on helping manufacturers achieve reliable compliance while maintaining development timelines.
