GMDSS Tester MRTS-7M

Marine Radio Test Set  MRTS-7M (GMDSS Multi Tester) is designed to carry out the mandatory periodical or annual surveys of all range of GMDSS equipment: AIS Stations, EPIRBs, MF/HF/VHF Radios with DSC and NAVTEX receivers in accordance with IMO A.948 (23) or A.997(25), A.1020(26), resolutions and MSC.1/Circ.1252, MSC.1/Circ.1039, 1040 circular letters. 

Marine Radio Test Set  MRTS-7M is all-in-one now.

The MRTS-7M is the device capable to provide accurate, independent operation test of the following equipment:

  • VHF receiver-transmitters
  • VHF DSC Controllers
  • VHF Watch Receivers
  • AIS Class A, AIS Class B, AtoN, AIS Base stations
  • AIS-SARTs
  • EPIRB, PLB
  • MF/HF radiotelephone equipment
  • MF/HF DSC Controllers
  • MF/HF Watch Receivers
  • NAVTEX equipment
  • 9GHz SART (optionally)

The GMDSS Multi Tester MRTS-7M is specified equipment for radio inspectors performing mandatory, periodical surveys of ship-borne communication equipment.

The tester allows ensuring the GMDSS equipment meets the appropriate performance requirements.

The Marine Radio Test System MRTS-7M is capable to transmit and receive the signal by:

  • broadcast antenna
  • direct connection by means of power sensor meter, attenuator and cables (conductive measurements)

All the test procedures are provided in accordance with international standards, such as:

  • IMO A.948 (23) or A.997(25), A.1020(26) resolutions (for marine radio stations);
  • The circular letter MSC.1/Circ.1252 (for AIS stations);
  • IMO Circular MSC.1/Circ.1039, 1040 (for C/S beacons);
  • IMO Resolution A.802(19), SOLAS-74/88 (for SART).

 

The MRTS-7M has a newest software, designed to make survey work easier.

The device can be connected by means of standard USB A - USB B cable. Special software is available for download. 

The software is compatible with Windows, MAC OS X and Linux. It provides possibility of automatic generation of IMO-like reports for all types of tested equipment. Even more, now a surveyor can generate one combined report of all the safety equipment tested on a vessel. 

A surveyor’s paper work can be now reduced to minimum: just generate a report, print it and sign! Or save it and send by e-mail. Add your company header with the logo and contacts in the user's profile, thus the test reports will be automatically generated with the header selected.

Linux, OS X and Windows 10 don’t require any drivers installation. For Windows 7 and earlier versions FTDI driver should be installed for proper connection on first run.

Windows 32 bits is supported.
