  • Anti-Jam protection in dynamic multi‑jammer scenarios
  • Embedded GNSS Receiver
  • RF Up-converter capabilities for external GNSS Receiver connection
  • Exceptional Anti-Jamming performance
  • Different Configurations an different requirements
  • Based on NTLab’s ICs
  • Compact enclosure system for fixed and dynamic applications
  • Anti-jam protection on land, at sea, in the air


The three bands GNSS receiver with anti-jamming capabilities, which can output accuracy position, velocity and time jam-free information even in dynamic multi‑jammer scenarios.

The product supports the GPS, GLONASS, Galileo, BeiDou, NavIC satellite constellations and can be employed for the land, sea, air platforms (including unmanned aerial systems) and fixed installations.

Spatial filtering methods are used to suppress jamming signals.

Interference mitigation is achieved by applying proprietary digital algorithms, creating dynamic nulls to give protection against narrowband and broadband interference sources.

Together with a phased array antenna (KV-AJA3), the Anti-Jamming GNSS receiver implements the Null-Steering algorithm based on classic auto compensator architectures with equalization channels, and jamming signals are separated from the GNSS signals. The direction of GNSS signals can be determined using phased array antennas (up to 3), and more than one jamming signal can be removed.
