Getting an FCC Global Maritime Distress and Safety System (GMDSS) Radio Operator/Maintainer License
The GMDSS Radio Operator/Maintainer License is a commercial FCC license. This license lets you operate and repair GMDSS equipment on ships.
This is actually two licenses combined into one. It covers both the operator’s duties as well as the technical maintainer’s duties.
Who Needs the GMDSS License?
Ships that are required by law to carry and use GMDSS equipment need a qualified person aboard. That qualified person needs to hold the appropriate FCC GMDSS license. Large commercial vessels fall under this rule. So do certain passenger ships. If you want to work on these vessels as a radio officer, you’ll need this license.
Step 1: Understand the GMDSS Exam Elements
This license requires passing multiple exam elements. You’ll need to pass FCC Element 1, which covers basic radio law. Additionally, you’ll need to pass the FCC Element 3 exam, which covers general electronics. Next, you’ll need to pass FCC Element 7, which covers GMDSS operating procedures. Finally, you’ll need pass Element 9, which covers GMDSS technical maintenance and troubleshooting.
Each element is a separate test. You can take them one at a time or in one sitting. If you already have a ham radio license, you may be credited for already passing some of the elements, such as FCC Element 1 and FCC Element 3.
Step 2: Study the Material
Study guides exist for each element. Look for materials from GMDSS-focused publishers. The publications will likely cover satellite communication systems, and distress signaling procedures. They also likely cover radio equipment repair and diagnostics.
Give yourself several months to prepare. This material is technical. It’s aimed at working marine radio professionals, not hobbyists (although some ‘hobbyists’ like the author have passed this test).
Step 3: Find a COLEM
You can’t test directly through the FCC. You test through a Commercial Operator License Examination Manager. These groups are called COLEMs. The National Radio Examiners and the National Association of Radio and Telecommunications Engineers both offer this testing. Search their websites for exam locations, dates, and examination costs.
Step 4: Take the Exams
Sit for each required element. Passing scores typically run around 75 percent per element. The COLEM issues you a Proof of Passing Certificate for each element you clear. Keep copies of these. You’ll need them for your actual license application, which some COLEMs will file online for you.
Step 5: Apply to the FCC
File FCC Form 605. Submit it within 365 days of passing your exam elements. Include your Proof of Passing Certificates. As noted aboe, COLEMs handle this filing for you electronically.
Step 6: Pay Any Required Fees
Fees can change, so check the current FCC fee schedule before applying. Your COLEM can usually tell you the exact current cost.
Step 7: Receive Your License
Processing typically takes a few weeks. Once issued, this license doesn’t expire like some commercial licenses do. Check current FCC rules to confirm, since license terms can be updated.
You can now legally operate and maintain GMDSS equipment aboard vessels that require it.
