AIMS-certified by the Department of Defense (DoD)

Viasat offers a comprehensive, end-to-end IFF solution, including the world’s first and only Air Traffic Control Radar Beacon System, Identification Friend or Foe, Mark XII/Mark XXIIA, Systems (AIMS)-certified IFF environment generation test set. This ensures users have the confidence they need before entering the battlespace — delivering a realistic flight experience.

Testing your RF communication systems

Speed flight tests and time to market with:

  • A realistic signal environment: Simulated environment generates real RF
  • A high-density RF signal environment: Hundreds of independent signals
  • Collision avoidance: Generate scenarios to ensure safe maneuvers to help prevent mid-air collisions
  • Realistic flight training: Ensure pilots are equipped to handle high-density environment/crowded airspace
  • Independent platform motion: 6 degrees of freedom (DoF) motion models
  • Independent RF signal generator control: Frequency, amplitude, delay, doppler, pulse characteristics, and more
Lab-tested, environment proven

If your avionics survive in the lab, then they’re ready for combat.

Systems designers rely on our signal modeling expertise to help successfully launch better avionics and communications systems on time and under budget. We offer RF signal generators for a variety of testing:

  • Unit testing
  • Dense communication testing
  • Surveillance testing
  • Effects of jamming tests
Radio frequency generator VRG-1000

Designed for testing IFF systems, Viasat’s Radio Frequency Generator (VRG-1000) includes an industry-leading 50 independent IFF interrogator and 25 independent transponder platforms. This portable test set brings high-density signal testing on-location to your installed or in-development IFF system, so you can replicate crowded airspace and reduce flight test time by evaluating your system in a lab. For advanced antenna testing, a sum and difference channel configuration (VRG-1000SD) is available upon request.

The F-35 Joint Strike Fighter solution

Lockheed Martin Aeronautical Systems used a Communication, Navigation, and Identification (CNI) Function Stimulator (CFS) for avionics testing of F-35 Lightning II aircraft, also known as the Joint Strike Fighter. Avionics systems complexity in state-of-the-art fighter aircraft requires realistic test environments and accurate signal representation. Viasat RF signal generators:

  • Provided a true-to-life CNI test environment
  • Reduced the cost of in-flight testing
  • Used in the Verification and Validation Facility (VVF) at Eglin Air Force Base, Florida
