Domestic electronic marine instruments, navigation equipment and communications equipment technique for a ship is very falling behind compare with Japan or European countries. Especially, there are no organized cooperation systems in terms of standardization activity. Because of this reason, the companies, which make electronic marine instruments, navigation equipment and communications equipment, have lots of problems with interfacing each device.
Presently, there is a trend that domestic products follow IEC61162-1/2.
In this case, however, wiring is too complex and when a user wants to add the other device, due to lack of NMEA signal out port or no composition of Isolation, it needs additional device, such as NMEA Buffer.
If you develop the device which is supporting IEC61162-3 standard protocol, you will be able to solve these all problems. Besides, you are able to make a lot of expectative effects.
By materializing the protocol to support IEC61162-3 standard, I have learned about standard protocol perfectly and it will apply to the other company's product, as a crucial technique. Also, it is expected to making a profit both in a domestic market and in an oversea market.
In this paper, I would like to introduce NMEA standard, such as IEC61162-1 (NMEA0183), IEC61162-2 (NMEA0183-HS) and IEC61162-3 (NMEA2000), and the way of approaching to protocol design.
Also, I will introduce CAN and materializing stack to support IEC61162-3. Later then, for MiTS system I am going to deal with TCP-IP protocol and materializing stack for E-Navigation.
