Controlled GNSS threat environments for receiver robustness testing.
This product family is separate from standard GNSS signal simulation. Signal simulators create nominal or degraded navigation signal environments. Spoofing and interference systems create controlled RF threat conditions to evaluate whether a receiver can detect, tolerate, reject, or recover from hostile or disruptive signal behavior.
These systems are for authorized testing and evaluation only. Deployment and operation must comply with applicable laws, spectrum regulations, shielded-lab requirements, and internal governance controls.
The ASG series supports GNSS spoofing simulation for anti-spoofing feature verification, detection threshold characterization, receiver behavior analysis, and integration into larger resilience test benches.
The JSG series supports interference and jamming test workflows across GNSS navigation bands and RDSS-related bands, enabling anti-jamming performance evaluation under repeatable RF interference conditions.
Typical programs use these systems to reproduce controlled spoofing scenarios, characterize receiver tracking loss and reacquisition behavior, validate spoofing detection algorithms, and document navigation security performance before field deployment.
Choose the system by threat type, integration depth, and test workflow.
Use this table as an initial engineering selection guide. Final configuration should be based on receiver bands, RF connection method, target constellation, output level requirements, synchronization needs, and the resilience metrics you need to measure.
