There are several Server options for connecting TAK Products to one another.
- FreeTAKServer is an open source project for consumer and hobbiest use led by reddit user u/Tapawingos. You can find it on GitHub here. Note that FTS has not implemented encryption. If you want your connection to be secure, you need to run a VPN which is inconvenient.
- TAKServer is an application in Java developed by the Air Force Research Laboratory and BBN, a Raytheon Corporation. TAKServer is not publicly available, but a list of TAKServer TAK Licensees who might host you is available. If you are a First Responder, you can access it by registering at TAKMAPS.com.
- PAR Team Connect TeamConnect is a cloud-based computing technology that provides Geospatial awareness solutions for organizations using the Android Team Awareness Kit (ATAK).
- ZeroTAKServer. ZeroTAKServer isn't a server. Its a serverless configuration that allows a small network of ATAK/CivTAK users to communicate over a VPN.
Several companies have licensed TAK from AFRL and may be willing to setup, manage, and train users on CivTAK and TAKServer. Licensees have access to TAKServer.
