pytak 3.1.1

Python Team Awareness Kit (PyTAK) Module

PyTAK is a Python Module for creating TAK clients & servers.

This module include Classes for handling CoT Events & non-CoT Messages, as well as functions for serializing CoT Events. As a bonus, there are helper functions for classifying Aircraft attitude/affiliation/posture based on ICAO, Emitter Category, Flight Name, et al.

IF YOU HAVE AN URGENT OPERATIONAL NEED: Email [e-mail] or call/sms [phone]

Examples of TAK Clients using the this module:

• aiscot: Automatic Identification System (AIS) to Cursor on Target (CoT) Gateway. Transforms AIS position messages to CoT PLI Events.

• adsbcot: Automatic Dependent Surveillance-Broadcast (ADS-B) to Cursor on Target (CoT) Gateway. Transforms ADS-B position messages to CoT PLI Events.

• adsbxcot: ADS-B Exchange to Cursor on Target (CoT) Gateway. Transforms ADS-B position messages to CoT PLI Events.

• stratuxcot: Stratux ADS-B to Cursor on Target (CoT) Gateway. Transforms position messages to CoT PLI Events.

• aprscot: Automatic Packet Reporting System (APRS) to Cursor on Target (CoT) Gateway. Transforms APRS position messages to CoT PLI Events.

See also:

• pycot: Python Cursor on Target (CoT), a Python Module for serializing CoT Events, for use with TAK clients & servers.

Usage

The following Python 3.7 code example creates a Cursor on Target Client that gets events from a CoT Event Queue and transmits them to our destination URL using TCP. Events are put onto the Queue by the Message Worker (QED). Events are expected to be serialized using the pycot Module:

#!/usr/bin/env python3.7
import asyncio
import urllib
import pytak

loop = asyncio.get_running_loop()
tx_queue: asyncio.Queue = asyncio.Queue()
rx_queue: asyncio.Queue = asyncio.Queue()
cot_url: urllib.parse.ParseResult = urllib.parse.urlparse("tcp:fts.example.com:8087")

# Create our CoT Event Queue Worker
reader, writer = await pytak.protocol_factory(cot_url)
write_worker = pytak.EventTransmitter(tx_queue, writer)
read_worker = pytak.EventReceiver(rx_queue, reader)

message_worker = MyMessageWorker(
    event_queue=tx_queue,
    cot_stale=opts.cot_stale
)

done, pending = await asyncio.wait(
    set([message_worker.run(), read_worker.run(), write_worker.run()]),
    return_when=asyncio.FIRST_COMPLETED)

for task in done:
    print(f"Task completed: {task}")

Requirements

PyTAK requires the FFI Library libffi (or libffi-dev), to install follow these instructions.

Debian & Ubuntu:

$ sudo apt-get install libffi-dev

RedHat, Fedora, CentOS:

$ sudo yum install libffi-devel
# or
$ sudo dnf install libffi-devel
