This module extends the capabilities of STK Communications with very fast, site-specific path loss predictions for communication links in urban environments.
The extension offers an unmatched combination of fidelity and speed, as compared to empirical and full-physics alternatives, across a broader range of frequencies and link geometries. These attributes make it the ideal choice for defense and intelligence applications involving trade studies, time-based scenarios and coverage analysis.
Urban path loss predictions are seamlessly integrated with STK's analytic models of moving platforms, communication systems and ISR sensors. This provides a valuable mission perspective for a variety of applications including tactical mobile communications, net-centric ISR, cyber warfare and urban tactics.
The Urban Propagation Extension, which requires a UProp license to use, is installed from the Urban Propagation Extension install media to your STK install area.
How It Works
The Urban Propagation Extension uses site-specific building geometry for correspondingly higher fidelity results. Employing the well established Uniform Theory of Diffraction, a triple-path geodesic model computes three dominant paths from the transmitter to the receiver: one in the vertical plane and two in the horizontal plane (clockwise and counter-clockwise). Received powers from these three paths are combined to estimate total signal strength at the receiver.
Using rapid ray tracing techniques and efficient diffraction methods, loss results are returned in milliseconds depending upon the size and complexity of the urban environment, and the locations of the transmitter and receiver. These almost instant computation times allow for trade studies, time-based scenarios involving moving platforms, and coverage analysis of large areas.
