nmea data

NMEA is a set of standard information that defines the output of the receiver. There are several different formats, each of which is an independent ASCII format that separates data streams. The data stream length ranges from 30 to characters, the output is usually selected at intervals per second. The most commonly used format is "GGA". It contains the positionin

In the past few days, GPS on WM wanted to obtain satellite data and found some information. There are two possible methods: 1, the Traditional GPS Programming Method reads data from the GPS device through the serial port, parses and processes the data. 2. Apply the gpsid function library provided by Windows Mobile to interview the Traditional GPS programming 1 fo

NMEA is the abbreviation of National Marine Electronics Association (National Maritime Electronics Association. The Association is a private institution dedicated to research on marine electronic devices and has developed NMEA standards for communication interfaces and protocols between GPS (GPS) electronic devices.

To share with you, but also for the future will not forget.NMEA protocol in general, relatively simple, is a relatively mature weather protocol.There are several main parameters and their formats: Wind speed and wind direction; Air temperature; Soil te
