Simple module to handle serial based NMEA GPS devices
npm install serialgpsSerial NMEA GPS Module
======================
This module makes use of the serialport and nmea modules to simplify data collection from a GPS device.
Installation
============
Install with
``
npm install serialgps
Usage
=====
Simple usage can be found in main.js
`
//include the module
var serialgps = require('serialgps');
//create a new instance. arguments are serial port and baud rate
var gps = new serialgps('/dev/ttyO1',9600);
//monitor for data
gps.on('data', function(data) {
console.log(data);
});
`
You may also listen for a specific NMEA message type, any of
* fix - GGA message
* geo-position - GGL message
* nav-info - RMC message
* track-info - VTG message
* active-satellites - GSA message
* satellite-list-partial - GSV message
For example,
`
gps.on('fix', function(data) {
console.log(data);
});
returns the following...
{ type: 'fix',
timestamp: '140554.000',
lat: '5245.5061',
