GMDSS (Global Maritime Distress Safety System) 

GMDSS består av en rekke systemer, noen er nye, men mange har vært i funksjon i en årrekke. Systemene er ment å dekke følgende funksjoner: varsling (inkludert angivelse av posisjon for enhet i nød), koordinering av søk og redning, lokalisering, kringkasting av maritim sikkerhetsinformasjon, generell kommunikasjon og bro til bro-kommunikasjon. Behov for radioutstyr er i GMDSS avhengig av skipets seilingsområde, i motsetning til tonnasjen. GMDSS spesifiserer også overlappende utstyr for varsling av nød, og angir kilder for nødstrøm.

GMDSS stiller krav til hvilket utstyr som skal befinne seg på fartøyet. Kravene defineres av hvilket havområde fartøyet seiler i. Det finnes 4 havområder definerte i GMDSS, såkalte Sea Areas

De 4 havområdene er:

  1. Sea Area A1, hvor blandt annet VHF, VHF m/DSC, Navtex, EPIRB, VHF nødkommunikasjonssett og SART inngår

  2. Sea Areas A1+A2, hvor det samme som A1 i tillegg blandt annet MF TX + RX radio inngår. 

  3. Sea Areas A1+A2+A3, som A1 og A2 i tillegg blandt annet MF DSC, Inmasat C eller Iridium, EGC inngår.

  4. Sea Areas A1+A2+A3+A4, som A3 i tillegg blandt annet Radiotelex.


Landor Larsen Elektronikk leverer all type utrustning som inngår i IMOs GMDSS krav.

In 2018, the IMO’s Maritime Safety Committee (MSC) recognized Iridium as a provider of GMDSS satellite services. In early 2020, these GMDSS services, hereunder: Distress Alert, Safety Voice, and Maritime Safety Information (MSI) will be available via the LT-3100S GMDSS system, a terminal developed by Lars Thrane A/S.

The LT-3100S GMDSS system is designed for all IMO vessels and will be an alternative to the Inmarsat C. The LT-3100S GMDSS system meets all standards and certification requirements needed for worldwide maritime satellite communications equipment (MED, Wheelmark).
