Pilots and payload operators using the VENOM training suite for Unmanned Aerial Systems (UAS) use Calytrix's Comm Net Radio (CNR) for simulated radio communications during training. CNR-Sim lets VENOM pilots and payload operators communicate realistically with other role players in the training scenario, including Air Traffic Control, Command Centers, and other aircraft. CNR-Log records the simulated radio traffic for After Action Review (AAR).

The Virtual ENvironment Operations Module, VENOM, from Legion Training and Simulation and Roy Aircraft and Avionic Simulation, is a new, low cost, ultra high fidelity Modeling & Simulation suite for UAS operations training. VENOM is fully configurable to match any UAS Platform, Sensor Payload, and Mission, including Fixed-Wing, Helicopter, Multi-Rotor, and Experimental platforms.
