Marine electronics
Marine electronics refers to
Marine electronics devices include chartplotter, marine VHF radio, autopilot and self-steering gear, fishfinder and sonar, marine radar, satellite navigation device, fibre optic gyrocompass, satellite television, and marine fuel management.
Communication
The electronics devices communicate by using a protocol defined by
In recent years, the International Electrotechnical Commission (IEC) has created a new standards suite for "Digital interfaces for navigational equipment within a ship". This is known as IEC 61162 and included NMEA 0183, NMEA 2000 and LWE.
Additionally, different suppliers of marine electronics have their own
- A+T Instruments has ESP Ethernet over Ships Power
- B&G has FastNet
- Furuno has NavNet ("NavNet" refers to a product family, and is not a communications protocol. Furuno uses industry standard NMEA 0183, NMEA 2000, and standard Ethernet for communications protocol in their products)
- Mastervolt has CZone
- Nexus has FDX
- Raymarine has Seatalk / SeatalkNG
- Simradhas SimNet
- Stowe has Dataline

Industry
Some manufacturers specialize more in equipment for commercial vessels such as tankers and general cargo vessels. This industry is relatively small with worldwide sales of $3.2 billion in 2015. The top manufacturer was Japan-based
