Python Team Awareness Kit (PyTAK)

PyTAK is a Python library for building TAK clients, servers & gateways — things that send and receive Cursor on Target (CoT) data on TAK networks.

Install

python3 -m pip install pytak

Quick example

import asyncio, xml.etree.ElementTree as ET
from configparser import ConfigParser
import pytak

class MySender(pytak.QueueWorker):
    async def handle_data(self, data):
        await self.put_queue(data)
    async def run(self):
        while True:
            root = ET.Element("event", version="2.0", type="t-x-d-d",
                              uid="myMarker", how="m-g",
                              time=pytak.cot_time(), start=pytak.cot_time(),
                              stale=pytak.cot_time(3600))
            await self.handle_data(ET.tostring(root))
            await asyncio.sleep(20)

async def main():
    config = ConfigParser()
    config["mytool"] = {"COT_URL": "tcp://takserver.example.com:8087"}
    config = config["mytool"]
    clitool = pytak.CLITool(config)
    await clitool.setup()
    clitool.add_tasks(set([MySender(clitool.tx_queue, config)]))
    await clitool.run()

asyncio.run(main())

Features

• TAK Protocol support — XML (TAK Protocol v0) and Protobuf (TAK Protocol v1, via takproto)
• Multiple transports — TCP, TLS, UDP unicast, UDP multicast (Mesh SA), UDP broadcast, file, stdout
• TLS client auth — PEM certs, PKCS#12 (.p12), password-protected keys
• TAK enrollment — automatic certificate enrollment from a tak:// onboarding URL
• Marti REST API — send/receive CoT via TAK Server's HTTP API (marti:// URL scheme)
• TAK Data Packages — import .zip pref packages containing server connection settings and certs
• FreeTAKServer compat — built-in rate-limiting mode (FTS_COMPAT)
• No required external deps — pure-Python asyncio core; optional extras for TLS enrollment and Protobuf
