GPS Anti-Jam Antenna Technology – GAJT™
Hexagon’s NovAtel approach to the threat of PNT from jamming is to build a range of compact and affordable anti-jam systems for land, sea, air (including unmanned aerial systems), and fixed installations.
GAJT Anti-Jamming Antenna System (AJAS)
GAJT Anti-Jamming Antenna System (AJAS) is a null-forming system that preserves the antenna's view of the GPS satellites while ignoring jammers, ensuring the satellite signals required to compute precise position remain available.
GAJT AJAS gives indications of jammer presence and direction-finding capability.
Our GAJT Products
The GAJT range of products provides anti-jam performance at a significantly lower cost than others and is available off-the-shelf for rapid deployment. GAJT works with any installed GPS receiver and is ready for M-Code.
New: GAJT-310 Anti-Jam Antenna
Huge anti-jam protection in a tiny package | New lower SWaP PNT protection from the anti-jam leader
The newest member of the proven GAJT team means you can protect all your platforms from jamming. Light and small, it's the best protection per gram you can get. You can even get it as an integrated enclosure (one piece) or a federated solution (separated anti-jam electronics and CRPA), so it is ideal for small platforms, like UAVs.
What sets the GAJT-310 apart?
Best protection per gram/ounce
Incorporating everything we learned from successful deployment of the GAJT-410 in all five military domains.
Use GAJT-310 to maintain time synchronization across platforms and sensors
Identify jamming sources with up to 10 degrees of accuracy.
Low latency means you can easily integrate the GAJT-310 into your operations. Learn more about how low-latency ensures worry-free anti-jam implementation.
Available as an integrated enclosure (one piece) or a federated solution (separated anti-jam electronics and 3-element CRPA) for integration into small platforms.
On the L1 and L2 bands with 30 dB of suppression.
