ATAK Messenger

Java library used to connect to an ATAK server and send Cursor-On-Target (COT) messages. This library has no dependencies and is released under a permissive MIT license.

Example Usage

The following class is used to connect to an ATAK server using a client and server certificate and relay ficticious drone locations every 10 seconds.

package com.example;
import javaxt.json.JSONObject;
import java.util.*;

public class Test {


  //**************************************************************************
  //** main
  //**************************************************************************
    public static void main(String[] arguments) throws Exception {

      //Parse atak config
        JSONObject atakConfig = Config.get("atak").toJSONObject();
        String host = atakConfig.get("host").toString();
        Integer port = atakConfig.get("port").toInteger();
        JSONObject certs = atakConfig.get("certificates").toJSONObject();
        java.io.File clientCert = new java.io.File(certs.get("client").toString());
        java.io.File serverCert = new java.io.File(certs.get("server").toString());


      //Instantiate atak messenger
        atak.messenger.Messenger atakMessenger =
                new atak.messenger.Messenger(host, port, clientCert, serverCert);


      //Connect to the server and start sending messages
        atakMessenger.connect(new atak.messenger.Messenger.Callback(){
            public void exec(){
                runSimulation(atakMessenger);
