GAJT-AE-N GNSS Anti-Jam Antenna Electronics

The GAJT-AE-N variant provides the antenna electronics for a Controlled Reception Pattern Antenna (CRPA) in a custom enclosure system.

GAJT-AE-N GNSS anti-jam antenna electronics are 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 CRPAs and cabling lengths to best meet the form factor requirements of their installation.

How it Works

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 Frequency (RF) feed, suitable for input to legacy GPS receivers.

Built For the Future

GAJT-AE-N comes in variants that protect either L1 and L2 or just L1 GPS signals in wide or narrow band. The wide bandwidth version ensures future compatibility with M-Code GPS.
