Compute urban environment losses in RF communications.

STK Urban Propagation extends the capabilities of STK Communications by computing diffraction losses in an urban environment and applying them to your link budget. Urban Propagation accounts for the impacts of buildings, terrain, and ground reflections. You can assess these effects to plan for link outages and asset redundancy, and to decide the placement of antennas, flight routes, and test locations.
