[Satellite Today – 4-7-08] Integral Systems Inc. subsidiary RT Logic has integrated its channel simulator and Satellite Tool Kit (STK) analysis technology from Analytical Graphics Inc., RT Logic announced April 4.
    RT Logic’s T400CS Channel Simulator is a phase-continuous RF/IF communications link simulator. When controlled by AGI’s time-dynamic, physics-based STK software engine, users can use visual development of communication link scenarios, without the need for user expertise in channel models, multipath, propagation effects, or orbital science.  
     Simple or complex scenarios are created within STK by selecting fixed or mobile uplink and downlink terminals or vehicles, along with actual or proposed satellites/aircraft/unmanned aerial vehicles.  To the resulting hardware-in-the-loop channel simulation, optional parameters such as terrain and fading can be easily applied for enhanced realism or worst-case analysis.
    STK will be integrated with RT Logic’s T400MSP Modular Signal Processor; further empowering classroom teaching and hands-on laboratory work in digital communications, satellite and payload operations, electronic warfare, defensive counter-space and communications interference management.
