Compact All-in-One Anti-Jam System (4-Channel)

Chelton’s latest GPS Anti-Jam development is the DACU4c; a compact, high performance system integrating a four channel CRPA along with advanced miniaturised GNSS Anti-Jam processing electronics.

The system is designed to maximise installation flexibility, through optional power and diagnostics data over RF (permitting the use of a single cable), and a highly reconfigurable baseplate to allow the mounting holes and connector type/position to be tailored to the target platform.

Use of Chelton’s established and field-tested GNSS Anti-Jam core firmware provides a high degree of protection against complex threat scenarios and in highly dynamic environments. A software definable core allows future upgradeable ‘Signal Intelligence Apps’ to be hosted, providing the user with situational awareness of the battlefield environment and allows feedback into mission planning activities.

Anti-jam GPS nulling
and excision

The DACU mitigates narrow-band interference, using an excision process, and broadband interference by creating directed nulls in the antenna pattern. These techniques provide significant anti-jam protection even in highly dynamic, multi‑jammer environments.

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.

The DACU is designed for size and weight constrained platforms, such as small airborne and unmanned installations. 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.
