Product Description

the Spoofing Antenna is a new high-performance GNSS antenna that protects navigation systems against both suppression jamming and spoofing, giving users more than traditional anti-jamming-only designs. Built for demanding civilian and commercial platforms, it combines large-array interference mitigation, spoofing awareness and clean RF output in one integrated unit for applications that require stronger navigation reliability.

Product overview

The 16‑Element GNSS Anti‑Spoofing Antenna is a single-frequency anti-jamming and anti-spoofing antenna designed to process BDS B1I/B1C, GPS L1 and Galileo E1 signals while reducing the impact of interference at the receiver front end. Using a 16-element array and advanced signal processing, it can counter suppression jamming, spoofing and mixed suppression-spoofing attacks, making it suitable for platforms that need both signal protection and situational awareness.

A key difference from conventional anti-jamming products is its ability to do more than reject hostile energy. The 16‑Element GNSS Anti‑Spoofing Antenna can also identify spoofing-related threats, report interference conditions in real time and provide support for smarter system decision-making through jamming power, jammer count and spoofing source count outputs.

Key features

16-element array architecture for stronger spatial suppression and front-end protection.

Simultaneous defense against suppression jamming, spoofing and combined interference attacks.

Support for replay spoofing and generative spoofing detection/processing.

Up to 15 suppression jammers can be handled from different directions.

Up to 8 spoofing sources can be identified from different directions.

Integrated receiver optimized for strong interference environments and UAV applications.

Clean RF output after mitigation for downstream GNSS equipment.

Real-time interference awareness for power level, jammer quantity and spoofing source monitoring.

Installation and use

The unit is mounted with brackets and screws, and the installation guide recommends overhead mounting with airflow beneath the base for heat dissipation. The top side should face open sky for best GNSS reception, and any cover above the antenna should use L-band RF-transparent material with transmission of at least 92%.

16‑Element GNSS Anti‑Spoofing Antenna is suitable for civilian and commercial UAVs, autonomous systems, mobile platforms and other applications that need stronger protection against both interference and false-signal attacks.
