GAJT-410ML Product SheetGAJT-410ML
GPS Anti-Jam Technology (GAJT) forsmaller platforms
Jamming and interference are constant threats
Jamming and interference, whether intentional or unintentional, can seriously
degrade GNSS position, navigation and timing (PNT) availability—even to the pointof total solution denial. Jammers create excessive noise, overpowering the low
power GNSS signals and saturating the electronics in a GNSS receiver front end.
Methods are needed to suppress this interference so your GNSS receiver continues
to operate.

Battle-proven in smaller and lighter enclosure
The GAJT-410ML is a new design that builds on our achievements in battle-provenanti-jam technology in a smaller enclosure. It combines antenna array and null
forming electronics into an enclosure that is suitable for installation on a wide
range of land vehicles and other small platforms.

Easy to integrate

Benefits• Commercial off-the-shelf (COTS)• Low cost anti-jam protection
designed for smaller platforms• Easy to integrate• High performance anti‑jam protection
in dynamic multi‑jammer scenarios• Compatible with legacy and modern
GNSS receivers, including M-CodeGAJT-410ML is connected with a Radio Frequency (RF) cable which reduces
the need for multiple cables to penetrate armor or the need for costly platform• Provides situation awarenessmodifications. This is enabled by the Power Injector Data Converter (PIDC), inside
the vehicle, which provides clean power and data, and delivers the protected
GNSS signal back to the receiver. The PIDC can be supplied in an enclosure, and isavailable to license for installation into third-party equipment.

Situation awareness
The PIDC also provides the jammer status and Direction Finding (DF) capabilities ofFeatures• Affordable protection for GNSS
position, velocity and time
• 40 dB of interference suppression

GAJT-410ML across the single RF cable to provide situation awareness in addition
to anti-jam protection.

• Simultaneous GPS L1/L2, QZSS L1/L2,
SBAS L1 and Galileo E1 protection

How it works
GAJT-410ML mitigates interference by creating nulls in the antenna gain pattern inthe direction of jammers, providing significant anti-jam protection even in dynamic
multi‑jammer scenarios. The output of the GAJT-410ML is a protected, standard
RF feed, free from jamming and suitable for input to modern and legacy GNSSreceivers.

Protects GNSS navigation and precise timing receivers
GAJT-410ML protects GPS L1/L2, QZSS L1/L2, SBAS L1 and Galileo E1 signals. Thewide bandwidth of GAJT ensures compatibility with M-Code GPS.

• Supports M-Code on GPS L1 & L2
• Adaptive digital nulling• Jammer direction-finding
