RF Signal Environment Generation

A True-to-Life RF Environment in Your Lab

As the world’s RF signal environment grows increasingly complex and diverse, today’s communication systems must be able to perform in the midst of extreme signal depth and diversity. With Viasat RF Signal Environment Generation, you can ensure your communication systems are ready for the real world before operational deployment. 

RF Signal Environment Generation goes beyond simulation to generate a dense, dynamic, and realistic RF environment

  • Realistic Signal Environment. A simulated environment generating real RF
  • High-Density Signal Environment. Hundreds of independent signals
  • Dynamic RF Environment. Independent signal behavior
  • Behavioral Emitter Models. Coherent signals that react to the environment
  • Independent Platform Motion. 6 DOF motion models
  • Independent Signal Control. Frequency, amplitude, delay, doppler, pulse characteristics, and more...
  • Savings. Save millions in development, flight test, and speed time to market

If Your Avionics Survive in the Lab... Then They're Ready for Combat

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

  • Unit testing
  • Dense communication testing
  • Surveillance testing
  • Effects of jamming tests

IFF Mark XIIA Signal Testing: Seamless Mode 5 and Mode S System Integration

Designed for testing Identification, Friend or Foe (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.


An Example: The F-35 Joint Strike Fighter

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. The complexity of the avionics systems in state-of-the-art fighter aircraft requires realistic test environments and accurate signal representation. Viasat RF generators provided a true-to-life CNI test environment and reduced the cost of in-flight testing.

This CNI Stimulator is an integral part of the Verification and Validation Facility (VVF) for the U.S. Reprogramming Laboratory (USRL) at Eglin Air Force Base, Florida.


Why Viasat?

We've been building RF Environment Generators for almost 20 years. Our RF Signal Environment Generation surpasses ordinary simulation and computer modeling techniques to actually generate a true-to-life avionics environment with real signals of RF energy, including RF jamming and background signals, ensuring the most accurate analysis of communication system performance.
