NMEA to educate on distress signals

SEVERNA PARK, Md.—In response to a request by the U.S. Coast Guard, the National Marine Electronics Association (NMEA) is working to ensure that radio distress signals sent by mariners contain GPS information that will enable search and rescue (SAR) teams to locate vessels quickly and efficiently.

While there is protocol in place, boat owners often neglect to connect their distress communication devices to the GPS, and also neglect to register their Maritime Mobile Service Identity (MMSI) number.

In a Feb. 23 letter, Rear Admiral R.E. Day explained to NMEA President David Hayden that, “Of the roughly 100 digital selective calling distress alerts we are now receiving each month, approximately nine out of 10 do not have position information (i.e. do not have a GPS navigation receiver interconnected to their DSC-equipped VHF radio), and approximately six out of 10 have not registered their MMSI. Despite the promises DSC technology offers in significantly reducing the alerting and search time for mariners in distress, there’s little a Coast Guard watchstander can do after receiving a distress alert with no position information, using an unregistered MMSI, and having no follow-up voice communications.”

Admiral Day said that both the MMSI registration problem and VHF/GPS interconnect issue can be addressed through public outreach, but he stressed that the “interconnect problem cannot be resolved absent a technological solution.”

“NMEA will do everything we can to help solve these issues, as part of our continuing joint effort with the Coast Guard and the Federal Communications Commission (FCC) to improve safety at sea,” Hayden said. “The NMEA 0183 Standard Committee is already working on new specifications, and we will encourage our manufacturer and dealer members to educate the boating consumer about the need to link their DSC radios with a GPS and to register their MMSI numbers. But, at the end of the day, we can only recommend that boaters take these actions—we can’t mandate them. That job should be a collaborative effort between the Coast Guard and the FCC.”
