GAJT - GPS-Anti-Jam Technology

Overview

In the fog of war, accurate positioning is key to success. NovAtel and QinetiQ have produced the first single-unit GPS anti-jam antenna designed specifically for military land vehicles. GAJT (pronounced “Gadget”) nullifies jammers, ensuring the satellite signals required to compute precise position will always be available.

At just under 290 mm in diameter GAJT provides anti-jam performance comparable to much larger systems, but at a significantly lower cost. GAJT is a commercial off-the-shelf (COTS) product, providing short order lead times and quick deployment. It easily integrates into new vehicle platforms or can be retrofitted with GPS receivers and vehicle navigation systems on existing and legacy military fleets.

Manufactured in Canada and incorporating Canadian and UK technology, GAJT only requires Canadian and UK export approval, so exporting to authorized customers in foreign countries is greatly simplified.

• Seven antenna elements can create six independent antenna nulls
• Fully integrated anti-jam solution compatible with existing GPS receivers and vehicle navigation systems
• Minimal integration training necessary – externally mounted unit requires no additional electronics inside the vehicle, only power and a single RF cable required
• Significantly shorter order lead times than existing anti-jam systems
• Non-ITAR product to ease export to authorized customers
• GPS L1 and L2 with upgrade path for other GNSS constellations
• M-Code ready (24 MHz bandwidth)
