TAK Tracker is a less resource intensive app that allows you to passively feed location data into a TAK network of your choosing. Unlike the ATAK app, it features no maps, messaging or interaction with data packages. Despite these limited features, it could be useful for tracking individuals that do not have a need to actually interact actively with the TAK network, or if you have a spare Android End User Device, it could be used to track game objectives, vehicles or just about anything else you can think of.
You can install TAK Tracker by following the link above, or searching for “TAK Tracker” in the Google Play Store.
If your device is compatible you can download and import this datapackage. Be aware of limited compatibility for this app.
