Model and analyze real-world dynamic RF and optical communications.

STK Communications simulates the performance of communications systems in the context of their missions. With Communications, you can model all the physical components of a system, including the RF environment. Assess the impacts of a wide variety of conditions and interference. Conduct comprehensive link budget analyses. Create reports of the results and visualize them with 2D and 3D graphics.
