Shore Based Maintenance of GMDSS equipment

In order to ensure the operability of GMDSS radio equipment (under SOLAS-74/88, Regulations IV/15.6 and 15.7), at least two of the following methods should be used on ships navigating in sea areas A3 and A4: qualified maintenance and repair at sea; shore based maintenance; duplication of equipment. When the vessel is operating in the sea areas A1 and A2, it is sufficient to use one of these methods, or a combination of them, by the decision of the... Read more >>

Annual Radio & AIS Surveys. How they are conducted on ships

Regular and detailed inspections of ships and their equipment can significantly reduce the number of emergencies at sea, ensure the safety of navigation and the reliability of cargo transportation. The surveys are carried out by qualified inspectors representing independent surveying companies approved by classification societies to perform surveys. Classification societies establish the criteria for inspection to ensure compliance of the issued certificates with international maritime... Read more >>

What people say about our products?

Nicolas Hawa
Supervisor Service Engineer

Aeromarine  MRTS-7M is a trustful instrument that has been used by our Service Engineers in all our attendances onboard.

High reliability, light design, quality performance and accurate results.

A trustful partner to our services, because the Correct Results Matter to us.

Victor Panov
Radio officer
Communication & Radionavigation Group

A full check of the radio equipment on ships is one of the most important areas of our activity. Despite the fact that from the outside it may seem that this is exclusively a formality, the main part of which is the printing of pieces of paper - in fact this is a carefully worked out procedure, many of whose components remain behind the scenes - but we will tell about them later.

As usual - not a single comprehensive check passes without the MRTS-7M device. One device for all checks: send and receive DSC to the MF / HF and VHF; monitor the frequency and modulation; send a NAVTEX test message; and full check of the EPIRB.

Even power and SWR can be measured, but I, however, prefer to do this with a pointer device - it is exclusively my personal preference.

The approach “take last year’s report and rewrite all the data from there” is not our method. All measurements are honestly made, in the amount required by IMO. And here helps the software that comes with the MRTS-7M. You do not need to manually rewrite all the numbers - just connect the device via USB to a computer, log in with your account, fill in the data about the vessel. The program itself will generate a report in a convenient, readable form.

Recently purchased the "beacon tester 406 mini" for Viking Life-Saving Equipment in South Africa and I couldn't be any happier.

The device is nice and compact and can be used from your computer or mobile phone. Issuing a report is very easy and the device is very user friendly.

NOLA GULF Marine Electronics

NOLA GULF uses the MRTS-7M.

Not only do we use it on GMDSS annual surveys, we take it with us on most service calls. The multi function light weight design makes it convient to always have on hand.

The Auto AIS test feature and Simulate ship function performs better than any other tester I have used.
