Green Mountain Electromagnetics, Inc. is an EMC and Radio test laboratory. For 30 years, GME has been offering electronic-product manufacturers compliance testing to CE, FCC and military standards.
At GME, we offer quality testing alongside personalized service, creating positive long-term relationships with clients. Careful time and attention are taken to work with customers that experience Electromagnetic Interference in products.
Automatic Identification Systems (AIS) provide continuous RF signal and data transmission for ship identification using TDMA/DSC transmitters and TDMA/DSC/GPS receivers. GME can test the performance of these transmitters and receivers.
Applicable standards are IEC 61993-2, IEC 62320-1, IEC 62320-2, IEC 62287-1 for Class A/B AIS, AtoN and Base Stations.
Tests performed include verification of Operational and Performance Requirements, EMC Tests, Identification and Operating Modes, and Autonomous Mode.
All performance checks are also in accordance with the Test Plan designed by GME with the customer. The table below gives a detailed list of tests performed.
GME also provides accredited testing for Licensed Maritime and Aviation Radio Service for FCC Part 80 and 87 approvals using ANSI/TIA-603-D. VHF-radio and -navigation equipment approvals are handled quickly.
Additionally, GME methods and equipment are in accordance with International Standard IEC 60945 Ed. 4, “Maritime Navigation and Radiocommunication Equipment and Systems – General Requirements – Methods of Testing and Required Test Results (August 2002 w/A1:2008)” Paragraph 9, “Electromagnetic Emissions – Methods of Testing and Required Test Results,” and Paragraph 10, “Immunity to Electromagnetic Environment – Methods of Testing and Required Test Results.”

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.
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.
