GME – Marine electronics: EPIRBs, PLBs, Radio Communications

Since the early 1970s GME has been at the vanguard of marine electronics in the Australian region. The blending of hands-on experience with creative software engineering has produced a host of innovative GME Marine products including the world’s first VHF radio with totally integrated direct dial telephone facility, the compact size COSPAS/SARSAT compatible EPIRBs and the GR series of marine stereos. All proudly bear the GME logo. All GME marine products undergo stringent testing to ensure they will provide years of trouble free service in the harsh marine environment. We are also sensitive to product aesthetics; our goal is to achieve a harmonious balance between good looks and practicality.


EPIRBs and PLBs:

How does an EPIRB work?
When activated, an EPIRB transmits information identifying the unit (and therefore the registered owner) in a 406 MHz signal. The signal is relayed via the COSPAS/SARSAT satellite network to the relevant Rescue Co-ordination Centre where the most appropriate rescue response is initiated and co-ordinated. If the unit is a GPS equipped EPIRB, the GPS location details are included within the 406 MHz transmission, giving rescue authorities an accurate location to an accuracy of about the size of a football field within minutes. Without GPS, the location is calculated by triangulation, which may take significantly longer. 
Beacons are detected world-wide by the global satellite system, COSPAS-SARSAT, and are detected from anywhere on the Earth’s surface if they are deployed correctly. It is worth noting that the search and rescue response in each country will vary due to different levels of SAR resources and capability. It is recommended that you check locally the sort of SAR response you can expect. 
PLB vs. EPIRB– what is the difference?
The technology used in PLBs and EPIRBs is essentially the same, however there are differences due to the different ways in which these devices are intended to be used.
An EPIRB is registered to the vessel using the vessel MMSI number and is designed to operate at full power for a minimum of 48 hours. It must be self buoyant, and float in an upright orientation with the antenna clear of the water to aid rescue. Personal Location Beacons work in exactly the same way as EPIRBs by sending a coded message on the 406 MHz distress frequency which is relayed via the Cospas-Sarsat global satellite system. However, PLBs are designed to be carried on the person so they are much smaller, and are designed to be used anywhere in the world, on the sea and also on land. GME’s PLB is the only one currently available that also floats. PLBs, once activated, will transmit for a minimum of 24 hours. 

MT603G 406Mhz GPS EPIRB (Class 2):

Introducing the all-new MT603G water-activated, GPS-equipped Emergency Position Indicating Radio Beacon (EPIRB) from GME. The MT603G is the most advanced MEOSAR-ready 406MHz digital EPIRB on the market today. Designed, engineered and manufactured in Australia, the MT603G has obtained international Cospas-Sarsat approval. Boasting the latest advances in emergency beacon technology, the MT603G ensures the safety of your vessel and crew in emergency situations, regardless of your location.
The MT603G is able to be activated both manually, and automatically, when the unit is removed from the mounting bracket and deployed in water by the user. The MT603G features an integrated 66 channel GPS receiver, delivering greater position accuracy and faster location fix than previous models. Boasting zero warm-up digital technology, the MT603G acquires and transmits accurate latitude/ longitude and personal identification information to rescue authorities as soon as possible. In combination with a high-intensity, solid state strobe light and auxiliary 121.5MHz VHF homing transmitter, the MT603G is the ultimate in emergency beacon technology.
MT603 – This is the version without GPS.
MT603FG 406Mhz Float-Free GPS EPIRB (Class 2) – the most advanced MEOSAR-ready 406MHz digital EPIRB on the market today.he MT603FG is a Category 1 EPIRB, which means the unit will automatically deploy from the supplied ‘Float-Free’ housing via a hydrostatic release unit at a depth of 1.5 – 4 metres, with the beacon activating upon contact with water. The EPIRB may also be manually removed from the housing and activated by the user.


MT410G Emergency Personal Locator Beacon (PLB):

GME’s Accusat MT410G Pocket Pro+ 406MHz Emergency Personal Locator Beacon (PLB) with integrated GPS – has been leading the world’s PLB market due to it’s features and innovation. The MT410G Accusat Emergency Personal Locator Beacon (PLB) offers a massive 7 year battery replacement life, and a 7 year warranty, the unit also features a high intensity flashing LED, a ‘Non Hazmat’ battery pack for simple and cost effective transportation and a 50 search channel GPS receiver with top mounted Quad helix antenna to improve location accuracy to better than 100 metres typically – all contributing to the unique AccuSat advantage.
