A NMEA-0183 GPS Protocol parser
An example using the node-serialport library to read a stream of messages from a GlobalSat BU-353 USB GPS receiver:
var serialport = require('serialport');
var nmea = require('nmea');
var port = new serialport.SerialPort('/dev/cu.usbserial', {
baudrate: 4800,
parser: serialport.parsers.readline('\r\n')});
port.on('data', function(line) {
console.log(nmea.parse(line));
});
// { type: 'active-satellites',
// selectionMode: 'A',
// mode: 1,
// satellites: [ 29, 18, 21 ],
// PDOP: '',
// HDOP: '',
// VDOP: '',
// talker_id: 'GP' }
// { type: 'satellite-list-partial',
// numMsgs: 3,
// msgNum: 1,
// satsInView: 11,
// satellites:
// [ { id: '18', elevationDeg: 7, azimuthTrue: 214, SNRdB: 43 },
// { id: '21', elevationDeg: 5, azimuthTrue: 114, SNRdB: 34 },
// { id: '26', elevationDeg: 71, azimuthTrue: 234, SNRdB: 0 } ],
// talker_id: 'GP' }
To add custom codecs
var MyCustom = require('./MyCustom.js');
nmea.traditionalDecoders['MyCustomr'] = MyCustom.decode;
