Users can quickly build high-fidelity system models by customizing, to various levels of detail, STK communications system components. Receiver and transmitter models may be attached to other STK objects—such as satellites, aircraft, ships, facilities, ground vehicles, and planets—to facilitate rapid scenario building and analysis. STK/Communications has a number of available antenna models. Alternatively, antenna patterns can be imported from SATSOFT (formerly CPLAN), the ITU GIMROC database, or user-defined pattern files. Users can also define multi-beam antennas, compute the aggregate beam, and display the contours in 2D and 3D.

Complete link analysis can be computed over time using STK's satellite orbit propagation/geometry engine coupled with the defined receiver and transmitter properties. Time-varying constraints such as Doppler shift and bit error rate linked with a full range of environmental models enable STK/Communications to provide link performance analysis that no spreadsheet can match. It works with the STK/Coverage and STK/Attitude modules to compute and display jamming and interference analyses on coverage grids and attitude spheres, respectively.

The TIREM extension module is also available to use in conjunction with STK/Communications to bring an even higher level of fidelity to your analysis. Follow the link to learn more.
