Anti-Jam GPS DACU (8-Channel)

Anti-jam GPS nulling and beamforming DACU8b. An 8 channel, highly capable software defined GPS anti-jamming processor for use with a controlled reception pattern array (CRPA) antenna.

  • Nulling and beamforming broad-band interference protection
  • Compact and lightweight
  • In use on KAI KF-21

The DACU8b mitigates broadband interference by creating directed nulls and steered beams in the antenna pattern. These techniques provide significant anti-jam protection even in highly dynamic, multi‑jammer environments.

The DACU8b can be customised to suit a variety of EGI interfaces in order to received the required information for beam steering control. The DACU8b is in use on KAI KF-21 (formerly known as KF-X), using a Honeywell EGI.

The DACU is designed for size and weight constrained platforms, such as small airborne and unmanned installations, but is suited to larger sized aircraft. The DACU includes the ability to determine the direction of multiple spatially separated jammers with an accuracy of better than 5 degrees when the system is calibrated to the aircraft platform.

Chelton is able to provide a complete anti‑jam solution for the platform. Installations can make use of a variety of CRPA options and cabling lengths, to best suit the form factor requirements of the platform. The DACU interfaces the antenna array to the GPS receiver.
