How to interpret the decoded AIS data?

Could someone kindly point me to some reference on how to interpret the decoded data, as in what does mmsi, bitarray, sog etc refer to?

Ais: MMSI as String

In ggencoder lib the mmsi value comes as integer.
The ais definition says it is a 9-digit ID.
E.g. the base stations has 2 leading zeros.
I forgot it when I made the changes.

I did a short check for Signal K. There is no problem with the type change.
Are there other clients that come into trouble?

How to use ?

Hello , how could I use GeoGate in my project ?? I didn't find any documentation or tutorial . Please help .

No support for multipart AIS message decoding

Have you thought about adding support for multipart AIS message decoding?

From comments in the source file it appears that there is no support for this, but is it so that the original C++ code didn't have this either?

It may be caused by following code:

AisTcpFeed-adapter.js line 117

data.cmd= TrackerCmd.GetFrom.TRACKER; should be data.cmd=TrackerCmd.GetFrom.TRACK;

and _TcpClient.js line 171 may need to add data.valid = "";

 case TrackerCmd.GetFrom.TRACK:

            var update = true; // default is do the update

            // compute distance only update backend is distance is greater than xxxm
            if (this.stamp !== undefined) {
                var moved =  parseInt (this.Distance (this.stamp, data));

                // compute elapse time since last update
                var elapse  = parseInt ((data.date.getTime() - this.stamp.date.getTime()) / 1000); // in seconds
                var speedms = parseInt (moved/elapse);         // NEED TO BE KNOWN: with short tic speed is quicky overestimated by 100% !!!

                // usefull human readable info for control console
                data.moved   = moved;
                data.elapse  = elapse;
                data.valid = "";
               // if moved less than mindist or faster than maxspeed check maxtime value
                if (moved < this.controller.svcopts.mindist || speedms > this.controller.svcopts.maxspeed) {

CreateDev is never get called

Hi,
BackendStorage.prototype.CreateDev at file MongoDB-backend.js is never get called.
and due to that there is no "ALL_Devices" collections created.

also the variable this.logged at file _TcpClient.js is never set to "true".
it always not logged in.

I am trying to use following config for TK102 device ..
Gps103 : {info: "Tk102 Gps103" , adapter: "Gps103Tk102" , port: 8090}

Ship length

in encoder/lib/GG-AisDecode.js
The var this.length is used for message length and ship length.
So when I call it from Signal K there is always a value for ship length in all messages.

Some AIS feeds have talker IDs other than AI

A Signal K user reported that most of the messages in AIS feed available at 153.44.253.27:5631 are ignored.

The feed's data has prefix BS

!BSVDM,1,1,,A,H3m=CT0tlDL4000000000000000,2*25
!BSVDM,1,1,,A,13oOBn00000NIB@SoTEcDDHN0<0H,0*38
!BSVDM,1,1,,A,33eG6N0OiOPPnC0Q49irT8RL00n0,0*4A

Apparently this is already fixed for BSVDM in 6eaeac6 but not published to npm. Could you please publish it so that people can enjoy the fix?

Furthermore the talker does not really matter afaik, the messages are VDM and VDO, so a better check would be to just ignore the talker id and check the sentence id. I can provide a PR if you think that's the way to go.

How do you send command through GPRS protocol

I think this is the module ggserver.

Is there a command architecture implemented to send commands back to the device when the client is connected through the GPRS protocol?

If so, where can i extend it for other devices and learn about it's architecture?

jison dependency causing problems

People are trying to create Open Embedded linux images with Signal K Node server, which uses ggencoder as you know.

OE build process for applications with npm dependencies is not 100% equal to npm process. ggencoder's jison dependency is causing problems with the build process.

One particular problem is the mixed case package id in JSONSelect, used via jison dep in ggencoder: https://github.com/lloyd/JSONSelect/blob/master/package.json#L3. That is but one of the issues.

Would you consider dropping the jison dependency, as it is not used by the published module and is just that bit extra, just the command line tool? You could make it a dev dependency, so that if you run npm install in ggencoder it would get installed, but somebody using ggencoder as a dependency would not be affected by it?

AIS binary message decoding for weather data

Would it possible to add more binary message decodings to case 8?

One interesting message could be meteorological-hydrographic-data to get weather observations from AIS where available.

Versions 0.1.15 & 0.1.16 on NPM throw a TypeError: Cannot read property 'trim' of undefined

After updating to version 0.1.16, we're getting a TypeError when decoding the following multiline AIS sentence:

const sentences = [
  '!AIVDM,2,1,0,A,53brRt4000010SG700iE@LE8@Tp4000000000153P615t0Ht0SCkjH4jC1C,0*25\n',
  '!AIVDM,2,2,0,A,`0000000001,2*75\n'
]

This used to work fine. The error we're seeing:

TypeError: Cannot read property 'trim' of undefined
      at new AisDecode (node_modules/ggencoder/lib/GG-AisDecode.js:367:57)

Edit: version 1.1.14 works as expected, 1.1.15 & 1.1.16 throw the error.

ggencoder with AIVDO to npm

Would you be able to release AIVDO supported ggencoder version to npm?

Certain multi line ais do not decode correctly.

Just had a ship go by that sent this message:

!AIVDM,2,1,9,A,53Moi:81Qk8LLpQH000PD98T@D4r118Tp<E=<0153@f594ke07TSm21D,0*63
!AIVDM,2,2,9,A,hF@000000000000,2*73

Unfortunately the decoder seemed to ignore a lot of the data and only output this:

MySqlDb backend does not store data

Hi,
Thanks for developing this app - I managed to install and run GeoGate using DummyBackend on Windows 2012R2. However, when using 'MySqlDb' as backend, I'm unable to get geojson data from
[server]:4080/ajax/geojson.rest?format=json&key=123456789&cmd=list&group=all and MySQL database is still empty (no all_devices table)

My MySqlDb config file:

var PortBase = 4000;

var GeoGateConfig = {
    backend    : "MySqlDb",         // backend file ==> mysql-backend.js [default file]
    name       : "GpsdMySQL",     // friendly service name [default Gpsd-Track]
    inactivity : 900,             // remove device from active list after xxxs inactivity [default 600s]
    debug      : 7,               // debug level 0=none 9=everything

    "services"    :  {  debug: 4
// this controle console, you probably want it hyden behind your firewall
        , Telnet   : {info: "Telnet Console"  , adapter: "TelnetConsole" , port: PortBase +0}
        , Httpd    : {info: "Minimalist HTTPd", adapter: "HttpAjax"      , port:PortBase +80, debug:5}

// following apaters are TCP servers and wait for clients to connect
        , Gps103   : {info: "Tk102 Gps103"    , adapter: "Gps103Tk102"   , port:PortBase + 3, debug:6}

// phone applications typically some form of OpenGPRMC
        , Celltrac : {info: "CellTrac Android", adapter: "GtcGprmcDroid" , port:PortBase + 20, debug:5} // OpenGPRMC

    },

  "mysql": { // [should reflect your MySQL configuration]
hostname: "localhost",   // MySql hostname
basename: "gpsdtest",        // Basename base should exist
username: "gpsdtest",        // MySql username
password: "password"         // MySql password
    }
};

module.exports = GeoGateConfig;

This is the console screenshot - I'm able to receive GPS message from my phone (connecting to port 4020) - using iOS\GTSTracker:

This is MySQL (I've created the DB and User)

and this is the browser screenshot:

Using Dummy Backend, I successfully get:

I'm not sure whether it is caused by the server or the mobile app config. Any idea how I can resolve this? (I have used gpsdtracking with flatfile backend before, it is also unable to record location data sent by GTSTracker).

Thanks in advance!

GGsmsc TypeError: undefined is not a function

I just tried the library. It works with the command line client example, but with the following, I get the error

var GGsmsc = require("ggsmsc").GammuSms;

       , smsc    : ''  // your SMS gateway phone number
       , report  : true          // enforce delivery report when sending

       for (var sms in message) {
