To determine requirements for communications missions and ultimately utilize derived mission data, engineers use AGI
technology to determine all aspects of their communications systems. The STK/Communication module allows users to
model receivers and transmitters within the system on satellites, ground systems, or aircraft and can calculate a
complete link budget for any or all communications links over any period of time. Complex multi-hop systems can be
accurately modeled, while interference analysis and the evaluation of electronic systems for Electronic Protection
(EP), Electronic Attack (EA), and Electronic Support (ES) can be applied to the mission. Output such as BER
performance, C/N, antenna noise temperature, and interference values are readily available.
