Product Description

The Antenna is a newly released 8‑element GNSS antenna that protects against both suppression jamming and spoofing, giving civilian and commercial platforms a stronger navigation defense than conventional anti-jamming-only designs. It supports BDS B1I/B1C, GPS L1 and Galileo E1, while combining interference mitigation, spoofing awareness and clean RF output in one integrated unit.

Product overview

The S8180 is built for applications that need more than simple jammer suppression. With advanced array signal processing, it can counter suppression jamming, spoofing and combined suppression‑spoofing attacks at the receiver front end, helping maintain stable navigation signals in complex RF environments.

In addition to filtering hostile interference, the antenna provides real-time awareness of the local signal environment by reporting suppression jamming power, suppression jamming count and spoofing source count. This gives system integrators and operators more visibility into signal conditions and supports smarter decision-making for UAVs and other autonomous platforms.

Key features

8‑element array architecture for stronger anti-interference performance and better front-end signal protection.
Simultaneous protection against suppression jamming, spoofing and mixed attack scenarios.
Support for replay spoofing and generative spoofing processing.
Capability to handle up to 7 suppression jammers from different directions.
Capability to identify up to 4 spoofing sources from different directions.
Integrated receiver optimized for strong interference environments and UAV applications.
RF output provides a cleaned navigation signal after mitigation processing.
Compact, rugged housing with IP65 protection for outdoor deployment.

Installation and applications

The unit is mounted with brackets and screws, and overhead installation is recommended to improve airflow under the heat-dissipation base. The antenna top should face open sky for best GNSS visibility, and any cover above it should use L-band RF-transparent material with transmission of at least 92%.

The 8‑Element GNSS Anti‑Jamming & Anti‑Spoofing Antenna is suitable for civilian and commercial UAVs, autonomous systems and other professional platforms that need stronger protection against both interference and false-signal attacks.
