Examples of "nmea"
The electronics devices communicate by using a protocol defined by NMEA with two standards available, NMEA 0183 (serial communication network) and NMEA 2000 (controller-area network based technology). There is also Lightweight Ethernet (LWE).
The term "NMEA 2000" is a registered trademark of the National Marine Electronics Association. Devices which are not "NMEA 2000 Certified" may not legally use the NMEA 2000 trademark in their advertising.
It can do NMEA recording, playback (with selectable speed), and can jump to any position in NMEA files, skipping unneeded data.
The following are some of the companies that have registered with the NMEA for the purpose of producing NMEA 2000 certified products:
NMEA 2000 (IEC 61162-3) can be considered a successor to the NMEA 0183 (IEC 61162-1) serial data bus standard. It has a significantly higher data rate (250k bits/second vs. 4800 bits/second for NMEA 0183). It uses a compact binary message format as opposed to the ASCII serial communications protocol used by NMEA 0183. Another improvement is that NMEA 2000 supports a disciplined multiple-talker, multiple-listener data network whereas NMEA 0183 requires a single-talker, multiple-listener (simplex) serial communications protocol.
The NMEA 2000 standard was defined by, and is controlled by, the US-based National Marine Electronics Association (NMEA). Although the NMEA divulges some information regarding the standard, it claims copyright over the standard and the contents thereof are thus not publicly available. For example, the NMEA publicizes which messages exist and which fields they contain, but they do not disclose how to interpret the values contained in those fields. However, enthusiasts are slowly making progress in discovering these PGN definitions.
NMEA 0183 is a combined electrical and data specification for communication between marine electronics such as echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other types of instruments. It has been defined by, and is controlled by, the National Marine Electronics Association. It replaces the earlier NMEA 0180 and NMEA 0182 standards. In marine applications, it is slowly being phased out in favor of the newer NMEA 2000 standard.
NMEA 2000 connects devices using Controller Area Network (CAN) technology originally developed for the auto industry. NMEA 2000 is based on the SAE J1939 high-level protocol, but defines its own messages. NMEA 2000 devices and J1939 devices can be made to co-exist on the same physical network.
The only cabling standard approved by the NMEA for use with NMEA 2000 networks is the DeviceNet cabling standard, which is controlled by the Open DeviceNet Vendors Association. Such cabling systems are permitted to be labeled "NMEA 2000 Approved". The DeviceNet standard defines levels of shielding, conductor size, weather resistance, and flexibility which are not necessarily met by other cabling solutions marketed as "NMEA 2000" compatible.
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.
The NMEA standard is proprietary and sells for at least US$250 (except for members of the NMEA) as of June 2013. However, much of it has been reverse-engineered from public sources.
In the table above, PRN is the satellite's actual Pseudo-Random Noise code. NMEA is the satellite number sent by some receivers when outputting satellite information. ( NMEA = PRN - 87 ).
The NMEA 0183 standard uses two primary sentences for AIS data
specification describes the transport of NMEA sentences as defined in 61162-1 over IPv4. Due to
Spanner is a free program provided by Garmin for PCs running Windows 2000 or XP. It ‘translates’ live positional data from Garmin’s proprietary interface into NMEA 0183. Garmin’s proprietary interface data is only provided via USB whereas NMEA data is provided via serial port. Spanner overcomes this by creating a virtual serial port and thereby allowing a USB based Garmin GPS receiver to ‘speak’ with programs that require NMEA data. For users with Windows 7 and above, GpsGate Client is required.
AIS Equipment exchange information with other equipment using NMEA 0183 sentences.
Seatalk2 was a pre-standardization version of NMEA 2000 using square connectors.
NMEA 0183 is widely supported by navigation and mapping software. Notable examples include the following.
The 61162 standards are all concerning the transport of NMEA sentences, but the IEC
does not define any of these. This is left to the NMEA Organization.
