NMEA AT LARGE
MEJ: Please bring us up to date on IMEA—the International Marine Electronics Alliance.
Reedenauer: The IMEA just came off a very productive
board meeting at the NMEA Conference this past September. The IMEA bylaws have been revised, as these are the
map the board and staff use for projects and initiatives the
IMEA can work on and get involved with. I see 2019 as a
good starting point for IMEA forming alliances with other
entities in the marine industry worldwide.
The IMEA board has finalized the IMEA mission statement as follows: “Bringing together stakeholders worldwide
to expand the use of marine electronics through education
and promotion of standards.” IMEA has the subject matter
experts on their Board of Directors to assist any maritime
company with special projects.
IMEA does not have members; it intends to have allies
with which to form alliances. The IMEA board consists of
Chairman Johnny Lindstrom of Westport Yachts, Vice Chair
Jorge Arroyo of the US Coast Guard, Brian Tetreault of the
US Army Corps of Engineers, Ben Ellison of Panbo.com,
Sean Hatherley of Simrad/Navico, Phil Whitehurst of
Actisense, and Dr Yung Yu of the Korean Marine Electronics
Industry Promotion Association. If there are readers who are
interested in becoming involved with IMEA, please email us.
MEJ: NMEA OneNet has been in the beta testing period
for the past 18 months. Any significant modifications as a
result? When do you anticipate the new Ethernet standard
will be published?
Reedenauer: The OneNet beta testing group has identified 135 technical and editorial issues with the standard. At
the time of this writing, over 110 of these have been
resolved. The most work still lies within the security module
of the standard. As far as I know, NMEA is the only organization in the marine electronics world that performs inter-operability beta testing prior to releasing a data standard.
I would be lying if I said there have not been issues along
the way developing OneNet. The beta group started with
over 10 companies 18 months ago, and is down to about
four active companies. Priorities within companies and
projects take precedence over beta testing. NMEA under-
stands this. I am still confident that OneNet will be released
in 2019, but at the same time NMEA is very conscious that
all potential loopholes need to be closed before release.
MEJ: We recently reported on the many updates in the
new Version 4. 11 of NMEA 0183 that involve navigation
satellite systems. Anything else in the new version that we
should know about?
Reedenauer: Not really. NMEA 0183 is still advancing
in areas outside of the maritime space. The use in the recreational market has been on the decline for several years
while the increase of NMEA 2000 use in the recreational
market has taken its place. What the international market
will see regarding NMEA 0183 is expansion in AIS (
Automatic Identification System) and DSC (Digital Selective
Calling), primarily for the commercial and SOLAS (Safety of
Life at Sea) sectors.
Outside of maritime, the new Version 4. 11 will be used
by data providers, such as Qualcomm, Broadcom and Sam-sung, which need to utilize the sentences that support the
new NMEA 0183 satellite systems Beidou (China), QZSS
(Japan), and NavIC (India). The other initiative from NMEA
is to go after companies that have not legally purchased the
standard from NMEA. Unfortunately there are pirated versions of this standard on the web since the standard has
been out since the 1980s. Please be advised these versions
are older and are not recommended for use. If any member
comes across this information, please email NMEA directly.
MEJ: Similar question regarding NMEA 2000—any major
changes/additions/updates? Do you see the continued
expansion of use of NMEA 2000 by dealers or boat builders
outside the US?
Reedenauer: NMEA 2000 is becoming commonplace
on most small recreational vessels worldwide. Nearly all of
the major marine electronics manufacturers have adopted
the standard. It does not matter if an installer is working on
a project in New Zealand, Canada, Brazil, or anywhere in
Europe, chances of installing NMEA 2000 in some fashion
are almost guaranteed.
There is a major NMEA 2000 standard release scheduled
for February 2019. The standard is entering the maturity
stage, and refinements will be included with this release to
the main document and certification documentation. The

game, technology game changers and pondering a new business model.

conscious. This is cutting the sales aspect out for the
