  • Simultaneous GPS L1, L2, GLONASS L1, L2, Galileo E1BC, E5b, BeiDou B1, B2 Anti-jamming Navigation Solution
  • Multiply jammers interference resistance (up to 3 directions)
  • Anti-Jam protection in dynamic multi‑jammer scenarios
  • Exceptional Anti-Jamming performance
  • Based on NTLab’s ICs
  • Compact enclosure system for fixed and dynamic applications
  • Anti-jam protection on land, at sea, in the air



NTLab developed and produces the GNSS receiver with L1 and L2 signal bands anti-jamming capabilities, which can output accuracy position, velocity and time jam-free information even in dynamic multi‑jammer scenarios. The product supports GPS, GLONASS, Galileo, BeiDou  satellite constellations.

Spatial filtering methods are used to suppress jamming signals. The Anti-Jamming GNSS receiver, together with a phased array antenna (NTL-AJA2s or NTL-AJA2), 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 nullified.
