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.
