KV-AJ3-OEM Triple band Anti-Jamming OEM GNSS Module

Category:
  • Separate units: Anti-Jamming OEM GNSS module and active phase antenna array (KV-AJA3-OEM)
  • Three band Anti-Jam protection
  • Multiply jammers interference resistance (up to 3 directions)
  • Anti-Jam protection in dynamic multi‑jammer scenarios
  • Embedded GNSS Receiver
  • RF Up-converter capabilities for external GNSS Receiver connection
  • Exceptional Anti-Jamming performance
  • Based on NTLab’s ICs
  • Easy adaptation to various applications
  • Small size and weight

 

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-OEM), 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.

The system provides significant jamming protection even in dynamic multi-jammer scenarios both under narrowband and broadband interferences.
Anti-jamming OEM GNSS module is designated for the navigation data (positioning, velocity, time) determination using GPS, GLONASS, Galileo, BeiDou, NavIC satellite constellations
