    GeoGate

    GeoGate is an opensource GPS/AIS tracking server framework, that enable easy integration of multiple GPS trackers in WEB applications. It provides data acquisition drivers for typical tracker devices or phone's GPS apps. It handle multiple database backend, and support GeoJSON, AIS & NMEA encoding/decoding. It embed support for multiple classes of trackers, phone-apps, as well an NMEA & AIS simulator.

    GeoGate-Encoder [ggencoder]

    Is the component that support AIS & NMEA encoding decoding for GeoGate. This component is fully independent of GeoGate and can be use without any other references to GeoGate

    Install

      npm install ggencoder
    
      note: ./bin/Ais2JsonClient cli depends on async & jison but encoder/decoder themself do not depend on anything
    

    Cli Usage

      node ./node_modules/.bin/Ais2JsonClient --verbose --hostname=localhost --port=5001
    

    API Usage

      // import GeoGate encoding/decoding NMEA/AIS methods
      var AisEncode  = require ("ggencoder").AisEncode;
      var AisDecode  = require ("ggencoder").AisDecode;
      var NmeaEncode = require ("ggencoder").NmeaEncode;
      var NmeaDecode = require ("ggencoder").NmeaDecode;
    
      // decode and AIS message
      var decMsg = new AisDecode ("!AIVDM,2,1,1,A,55?MbV02;H;s<HtKR20EHE:0@T4@Dn2222222216L961O5Gf0NSQEp6ClRp8,0*1C");
      if (decMsg.valid) console.log ('%j', decMsg);
    
      // encode AIS message
      var encMsg = new AisEncode ({// class AB static info
            aistype    : 24,
            part       : 1,

            dimC       : 0,
            dimD       : 5
      }); if (encMsg.valid) console.log (encMsg.nmea);
    
      // decode NMEA message
      var decMsg = new NmeaDecode ('$GPGGA,064036.289,4836.5375,N,00740.9373,E,1,04,3.2,200.2,M,,,,0000*0E');
      if (decMsg.valid) console.log ('%j', decMsg);
    
      // encode NMEA message
      encMsg = new NmeaEncode ({ // standard class B Position report
             msgtype    : 2,
             cog        : 72.2,

             lat        : 36.91968,
      }); if (encMsg.valid) console.log (encMsg.nmea);
