KV-AJ1-OEM Single band Anti-Jamming OEM GNSS Module

  • Separate units: Anti-Jamming OEM GNSS module and active phase antenna array (KV-AJA1s-OEM or KV-AJA1-OEM)
  • L1-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 for external GNSS Receiver connection
  • Exceptional Anti-Jamming performance
  • Easy adaptation to various applications


Interference mitigation is achieved by applying digital null-steering algorithms to the signals, creating dynamic nulls in the antenna gain pattern to the direction of jammers. The system provides significant jamming protection even in dynamic multi-jammer scenarios both under narrowband and broadband interferences. Anti-jamming GNSS receivers are designated for the navigation data (positioning, velocity, time) determination using GNSS signals (GPS, GLONASS, Galileo, BeiDou)1 in the L1, L2, L5, E1BC, E5a, E5b, B1, B2 bands1 under intentional and unintentional interferences.
