The Standalone TAK Tracker, which allows users to be tracked on TAK Servers without having to install ATAK itself. There’s no map, and you don’t get to see where anyone else is, but its a great way to track people who are on your team but don’t need the complication of a map.
The interface is relatively simple, and supports certs.
You can download it here.
What format should the certs be in? I have the certs that are generated by Free TAK Server that work with ATAK but no matter what file extension I use TAK Tracker doesn’t give an option to select the files.
