JSG8000 Navigation Interference Source
Generate controlled GNSS and RDSS S-band interference signals for satellite navigation receiver anti-jamming performance testing, R&D validation, acceptance verification, and troubleshooting workflows.
For authorized laboratory testing, receiver anti-jamming verification, R&D validation, and controlled training environments only. Operation of RF interference equipment must comply with applicable spectrum regulations, test-site controls, and internal governance requirements. Confirm legal suitability and operating constraints before procurement or use.
Controlled interference source for receiver anti-jamming validation.
JSG8000 series navigation interference sources are designed for anti-jamming functional and performance testing of satellite navigation receivers. The system can transmit multiple types of interference signals across GNSS navigation frequency points and RDSS S-band interference scenarios.
Each device supports controlled channel configurations for receiver R&D, validation, acceptance testing, and troubleshooting workflows. JSG8000 fits inside the GNSS Spoofing & Interference Test product family as the dedicated interference source, distinct from ASG spoofing systems and distinct from standard GNSS signal simulators.
