The National Marine Electronics Association (NMEA) has developed a specification
that defines the interface between various pieces of marine electronic
equipment. The standard permits marine electronics to send information to
computers and to other marine equipment.
- 国际海洋电子协会制定海事设备的标准通信接口，本标准允许不同海事设备间通信。
and expect data to be in NMEA format. This data includes the complete PVT
(position, velocity, time) solution computed by the GPS receiver. The idea of
NMEA is to send a line of data called a sentence that is totally self contained
and independent from other sentences. All NMEA sentences are sequences of ACSII
symbols that begin with a '$' and end with a carriage return/line feed sequence
and can be no longer than 80 characters of visible text (plus the line
terminators).
几乎所有的应用程序提供并希望获取NMEA格式的数据。数据完整包括地点，速度，时间，
这些都是由GPS接收器计算得到。NMEA协议定义了发送数据帧的格式，包括自包含的信息，每种格式
都是相互独立的。所以的NMEA格式的帧都是以‘$’开头，回车换行符结束的ACSII字符串，该字符串不
超过80个字符。
