Evolution of EPIRB Testers

The phased implementation of the GMDSS began with the mandatory equipping of vessels with satellite beacons. Its introduction made it necessary to manufacture EPIRB testers. IMO required the inspection of emergency beacons to be mandatory. According to its requirements, EPIRB testers must provide accurate measurement of the parameters and performance of the emergency beacon in volume of: Annual testing of 406 MHz satellite EPIRBs (Resolution MSC.1/Circ.1040/Rev.1 Revised Guidelines...

Evolution of testers for GMDSS radio equipment

The protection of human life at sea has reached a new level over the past three decades, - since 1992, the phased implementation of the GMDSS (the Global Maritime Distress and Safety System), developed by International Maritime Organization (IMO), began. The principles of the GMDSS are defined by the Regulations of Chapter IV of the International Convention SOLAS-74, as amended in 1988. By this time, satellite communication systems were widely used, providing fast and reliable... Read more >>

Posidonia 2020

Posidonia Exhibition 2020 is re-scheduled for October and our participation as exhibitors keeps in force; the place is the same – the Athens Metropolitan Expo. We fully support such preventive measures and believe that they will help to stabilize the situation.

Guidance on AIS devices agreed

The Sub-Committee endorsed a draft Safety of Navigation (SN.1) circular providing information to seafarers on the display of AIS-SART, AIS Man Overboard (MOB) and EPIRB-AIS devices, for submission to the MSC for approval.

GMDSS modernization on agenda

The modernization of the Global Maritime Distress and Safety System (GMDSS), e-navigation implementation and new and amended ships’ routeing proposals are among items on a busy agenda as the third session of IMO’s Sub-Committee on Navigation, Communication, Search and Rescue (NCSR) gets underway (29 February-4 March).

Completely new 406MHz BEACON Tester

We would like to introduce completely new 406MHz BEACON Tester in mini format. Tester is designed to test any COSPAS-SARSAT radio beacons. Tester can operate with mobile devices, such as mobile phones, laptops, tablets with Wi-Fi support.

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.

Fernando Rebolo

Definetely excellent products. I am user of the MRTS-7M and I became a big fan of it. Handy, light and reliable.

Willem Auret
Technical Director
Soremar Group

Very proud to say that Soremar Group uses the MRTS-7M with full options and additional 9GHz SART tester.

For us AEROMARINE SRT is just the obvious choice if you look at what is on offer. The fact that Radio Surveys require you to lug around all your equipment is one of the biggest factors that makes the MRTS-7M so useful.

It is the most complete and lightest "all in one" GMDSS tester available. AEROMARINE SRT also provides great software that uses cloud storage (with offline capabilities) to store all your data at no extra charge.
