GPS Devices integrate seamlessly with new Garmin NMEA Marine Network Architecture

We have touched the topic of the Marine Command Center new design which combines proprietary and NMEA 2000 based, (NMEA stands for National Marine Electronics Association, the US based NMEA defines and controls the purity and effectiveness of the network standardization), marine networking platforms, and integration trends  between leading technology firms including Garmin (GRMN) and Volvo in our previous articles: "New update to Garmin Marine Command Center Architecture" and "Researching new Marine Platform of Volvo Penta and Garmin navigation and communication alliance". Today we continue to explore this newest GPS-friendly Marine Network Architecture trend in more depth, from the power boat and sail yacht Captain's and boat maintenance Engineer's angle of view, in an attempt to understand better how the proprietary Garmin marine network is seamlessly integrated and pluggable with the NMEA standardized network, for the unified Marine Command Center installation on your sail yacht or power boat.

The all-inclusive universally pluggable Marine network architecture may utilize at least two networks: the Garmin Marine Network, which is proprietary and shown on the diagram below in red color, and the NMEA 2000 network shown in blue color. Garmin provides pluggable solution to combine both red and blue marine networks into one, simple yet robust, to install, manage and upgrade while it is being enriched with new devices and functionality. These are the blood vessels of the information exchange fabrics of the combined Marine Network allowing plug-in ability of GPS and other marine devices and sensors.

GARMIN GPSMAP 720s is NMEA compliant

The specific NMEA 2000 standardization specification targets marine data networks governing the fundamental electrical and data specifications for communication between marine electronic devices.  Such as GPS receivers, GPS chart plotters, GPS sonars and depth finders, GPS fishfinders, the oceanic, nautical and navigational instrumentation arrays, fuel and other tank level sensors, many of them listening to the heart beat of the marine vessel engine. One example of the NMEA 2000 compliant device is Garmin GPSMAP 720s Marine Chartplotter, or the one shown on the architectural diagram, the Gpsmap 5208. Any previously owned or brand new power boat and sail yacht can easily adopt the Marine Command Center GPS enabled and NMEA 2000 compliant marine network.


Garmin Marine Network Architecture NMEA 2000 pluggable


The blueprint for the typical NMEA 2000 "blue" marine network installation, at the first glance, seems to be pretty complicated. However, with Garmin Marine Network Expander, namely the Garmin GMS™ 10 Port Expander your boat would welcome on-board many more pluggable marine GPS devices and GPS navigational accessories. Same type network cabling is suitable for either "red" unit-to-unit and "red" unit-to-network connections, with proper adapters. Once you make sure you figured which adapters to use where it is not difficult to connect any combination of GPS sensors and GPS chartplotter displays. The Garmin GMS™ 10 Port Expander will take care of routing data between all components of the "red" network.

The Garmin nautical navigation Marine Network, on the other hand, the "red" one, is also plug-and-use by design and enjoys such features as being waterproof, simple to install and reliable. Naturally, the symbiosis of both networks shall have an outstanding results. As to the data speed, the Garmin data network system is based on the Ethernet-fast (100-megabit) solid foundation. The compatible GPSMAP chartplotters with built-in detection algorithms are capable of serving as the smart central network hubs to anchor the most important processing functionality.

They can automatically detect each newly added networked link and accommodate it. The "red" proprietary high-speed branch seamlessly connects compatible GPS antennas, course compass units (CCU) and GpsMap chartplotters as the are plug-and-play devices. Working together these GPS components access GPS position reference, detailed 3D-view charts, radar, sonar, XM and WX Satellite Weather information. The chartplotter's multifunction displays (MFD-s) automatically detect GPS peripherals upon connection to the network.
