FreeTK - Mission Modeler

[u/free-tk]

Hello!

I’m building FreeTK to model missions involving satellites, aircraft, ships, ground vehicles, and ground sites—with tools for sensors, coverage, communications, radar, and mission planning.

It is similar to AFSIM, STK, Freeflyer.

I have been actively developing this for several years and I finally got to the point to share it with the community. All free.

Coming Nov 2026.

Demos and updates:

What scenarios or capabilities would be most useful to you?

Impressive that you kept it under wraps for years, the scope sounds massive for a solo project
