Description

The GAJT-AE-N provides the antenna electronics for a Controlled Reception Pattern Antenna (CRPA) in a rugged enclosure. GAJT-AE-N is designed for size and weight constrained applications such as small airborne and ground unmanned platforms, where it is preferable to mount the antenna electronics inside the vehicle. Users can select from a variety of 4-element antenna array and cabling lengths to best meet the form factor requirements of their installation.

    GAJT mitigates interference by creating nulls in the antenna gain pattern in the direction of jammers, providing significant anti-jam protection even in dynamic multi-jammer scenarios. The output of the GAJT-AE-N is a standard Radio Freqency (RF) feed, suitable for input to legacy GPS receivers.
