Jamming and interference, whether intentional or unintentional, can seriously degrade GPS position, navigation and time availability – even to the point of total solution denial.  Our GNSS protection solutions provide resilience to protect the receiver against interference sources.


GAJT ®-410ML

The GAJT-410ML is the next evolution of NovAtel’s battle-proven anti-jam technology. It maintains the high levels of interference rejection performance as in the larger GAJT-710ML system, but in a lower size, weight and power (SWaP) design.

anti-jam performance

Simultaneous GPS L1 and L2 Operates with civil and military GPS receivers as well as M-Code.

Easy Integration

Integrates easily into new or legacy fleets and uses the existing Radio Frequency (RF) cable to supply data and power directly to the unit to reduce the need for costly platform modifications.

Low Size, Weight, and Power

Includes a combined antenna array and null forming electronics making it suitable for installation on a wide range of land vehicles.

Situational Awareness

Provides situational awareness by accessing access the jammer status and direction-finding (DF) capabilities.

GNSS Protection

GAJT ®-710 ML / MS

GAJT (pronounced “Gadget”) is the first single unit GPS anti-jam antenna appropriate for use with military land vehicles, networks and timing infrastructure. GAJT nullifies jammers, ensuring satellite signals necessary to compute position and time are always available.

Commercial off the shelf (COTS)

Immediate availability for urgent operational needs. Non-ITAR product to ease export to authorized customers.

Anti-Jam Performance

Simultaneous GPS L1 and L2 with an upgrade path for other GNSS constellations. M-Code ready (24 MHz bandwidth).

Can be Retrofitted

Compatible with existing GPS receivers and vehicle navigation systems.

Easy Integration

Minimal integration training required.

GNSS Protection


The GAJT-AE-N® variant is for applications where equipment size and weight should be minimised. It provides the antenna electronics for a Controlled Reception Pattern Antenna (CRPA) in a custom enclosure system.

Modular System

Designed for size and weight constrained applications, where it is preferable to mount the antenna electronics inside the vehicle.

Anti-Jam Performance

Protects either L1 and L2 or just L1 GPS signals in wide or narrow band. 

4 Element CRPA

Any 4-element CRPA can be used allowing for a range of form factors or bespoke designs.

M-Code Compatible

Wide bandwidth version ensures future compatibility with M-Code GPS.
