STK Communications QualNet Interface x64

STK Communications QualNet Interface x64 is a 64‑bit integration module that connects the Communications capability in Systems Tool Kit (STK) with the QualNet network simulator. It enables time‑synchronized co-simulation, combining STK’s high‑fidelity platform motion, geometry, and RF environment with QualNet’s detailed network protocol and traffic modeling. The result is an end‑to‑end view of communications performance—coverage, connectivity, routing, throughput, latency, and reliability—across terrestrial, airborne, and space assets in dynamic, mission‑realistic scenarios.

Key capabilities:

• Exchanges platform trajectories, antenna pointing, and link state data between STK and QualNet on each timestep
• Models mobility-driven topology changes with terrain and line‑of‑sight effects reflected in network performance
• Evaluates protocol behavior (e.g., routing and queuing) alongside RF link metrics such as path loss and interference
• Visualizes network status and performance metrics within STK’s 3D environment, with logging for post‑analysis
• Supports larger, more complex scenarios with 64‑bit memory addressing and improved performance
• Offers scripted and batch runs for trade studies and “what‑if” analyses

Use it to assess mission communications plans, de‑risk network architectures, and validate performance under realistic movement, environmental constraints, and traffic loads.
