US DoD certifies ViaSat's VRG-1000
ViaSat has received certification from the US Department of Defense (DoD) AIMS Program Office for its Radio Frequency Generator 1000 (VRG-1000), the company announced on 7 September.
The VRG-1000 replicates a crowded airspace, enabling users to perform realistic identification, friend or foe (IFF) testing. The system provides a lab environment to reduce flight test time and overall flight testing costs.
The VRG-1000 provides a precise, realistic simulation environment. The portable RF flight test generator uses an intuitive graphical interface and multiple simultaneous interactive interrogators or transponders to simulate a true flight experience.
The system leverages a computer-generated motion programme to provide accurate attenuation and delay of signals, mimics real-time coherent RF messaging in dense, dynamic signal environments, and uses KIV-77 cryptographic equipment for encoding Mode 4 and Mode 5 IFF systems.
The VRG-1000 is capable of testing both automatic dependent surveillance-broadcast and Mode 5 Level 2 technologies to source aircraft positioning and tracking. The radio also complies with Mark XIIA IFF specifications set forth by the DoD for use in high-density signal environments.
