The NMEA protocol is a standard protocol for exchanging information between the Global Positioning System (GPSQ) and other navigation devices and equipment. The NMEA protocol defines a set of message formats that can transmit information about GPS devices and sensors, such as position, speed, time, and azimuth.
Since the NMEA protocol is a standard protocol, almost all GPS devices and receivers support it, and it is often used to communicate with other devices and computers. For applications and devices that need to use GPS data, the NMEA protocol provides a simple and easy-to-implement method to obtain real-time information about location and navigation.
Common NMEA message types
These are identifiers for message types defined in the NMEA protocol, used to pass information between GPS receivers and other devices. Each identifier represents a different message type, for example:
Global Positioning System Fix Data
Geographic Position - Latitude/Longitude
GNSS DOP and Active Satellites
GNSS Pseudorange Error Statistics
GNSS Satellites in View
Recommended Minimum Specific GNSS Data
Course Over Ground and Ground Speed
Time and Date
What NMEA connectors can be used for GPS devices?
There are mainly these common connectors：M12,M8,M23,7/8''...
Premier Cable offers you a diverse selection of GPS connectors
M12 Connectors and cables
M12 is a circular industrial standard connector, commonly used for sensor and device connections in harsh environments. In marine GPS applications, the M12 connector is very suitable for use in marine and humid environments due to its waterproof and dustproof properties.
M8 Connectors and cables
M8 is also a circular connector, smaller than M12. It is usually used in space-constrained applications, has waterproof function, and is suitable for connecting small sensors and devices. In marine GPS systems, M8 connectors can be used to connect small GPS receivers or related accessories.
M23 Connectors and cables
The M23 is a larger circular connector that is typically used in applications that require high power and high-speed signal transmission. Due to its larger size and higher current carrying capacity, the M23 connector can be used in marine GPS systems to connect devices that require high performance, such as high-power antennas or data transmission devices.
7/8'' Connectors and cables
The 7/8'' connector is an industrial connector that is widely used for electrical connections of sensors and actuators. It has a high level of protection and can provide reliable connections in harsh environments. In marine GPS systems, the 7/8'' connector can be used to connect various marine sensors and GPS devices.
