Core Advantages

8-element Anti-Jamming Antennas array structure enabling spatial filtering and robust interference suppression from multiple directions.
Effective mitigation of broadband, narrowband, sweep, pulse, and combined jamming across B1, L1, E1 and extended G1 ranges.
Supports simultaneous suppression of up to seven independent jamming sources while maintaining useful satellite signals.
Integrated GNSS receiver option delivers position and velocity results directly through the data interface for simplified system design.
Wide DC input range and low typical power draw make it suitable for vehicles, vessels, unmanned platforms, and fixed installations.
Rugged enclosure, IP65-level sealing, and industrial temperature range ensure stable operation in outdoor and mobile environments.

Typical Use Cases

Navigation and timing for ground or airborne defense systems operating in contested RF environments.
UAV, aircraft, and maritime platforms requiring resilient satellite navigation and high availability of GNSS signals.
Critical infrastructure timing, communication base stations, and high-precision equipment exposed to potential interference.

Integration Options

The Anti-Jamming Antennas provides two working configurations: RF-only mode, where anti-jammed RF signals are delivered to an external receiver, and receiver mode, where internal processing outputs navigation data directly. Mode selection is performed via a serial interface, allowing system designers to adapt the product to different architectures with minimal hardware change.
