8 Channel Anti-interference module JAJ2-8

No.JAJ2-8
The product guarantees that satellite navigation data is not disturbed, including GPS, China Beidou, European Galileo and Russian Glonass. The anti-interference modules can all receive satellite signals, and main purpose of the module is to counteract the threat of interference guns and radar, ensuring that the navigation data of drones is not compromised interference, without losing position and yaw.
Features:
  • light in weight
  • dual bands antijam 1.2GHz & 1.5GHz
  • Built in positioning module, directly connected to flight control

SPECIFICATION

General description

Crown GNSS Anti-Jam Systems support critical missions by providing jam free GNSS signals and resilient PNT.
With its 4-element CRPA antenna, state-of-the-art digital controller and novel beamforming techniques JAJ2-8 eliminates interference to ensure uninterrupted operation of GNSS receivers in the presence of up to 7 jamming sources.
JAJ2-8 supports various messaging formats and integrates seamlessly with civil and military GNSS receivers deployed on land, sea, air manned/unmanned platforms and fixed installations. JAJ2-8 also offers an embedded high performance GNSS receiver as an option and allows SBAS signals to be utilized for increased accuracy and reliability.
In addition to CRPA, protection performance is further improved using adaptive notch filtering and pulse blanking.

Features:
  •  Protection against  up to 7 jammers
  • Easy to install
  • Plug and play integration into new or legacy platforms
  • Immediate availability for urgent operational needs
  • Compatible with all types of external GPS receivers and vehicle navigation systems, including M Code
  • Antenna and controller integrated as a single unit
  • Light weight and ultra compact size
  • Superior suppression performance
  • Embedded GNSS receiver option
  • Compatibility with military standards
  • Resilient PNT
