Jamming and Interference are Here to Stay
Jamming and interference, whether intentional or unintentional, can seriously degrade GPS position, navigation and time availability-even to the point of total solution denial. Jammers create excessive noise, overpowering the low power GPS signals and saturating the electronics in a GPS receiver front end. Methods are needed to suppress this interference so your GPS receiver continues to operate.
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 point of 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 lightweight anti-jam
GAJT-AE-R is the antenna electronics for a Controlled Reception Pattern Antenna (CRPA) with a mounting bracket to simplify integration into the user’s platform. GAJT-AE-R is designed for size and weight constrained applications such as small airborne and ground unmanned platforms where it may be preferable to mount the antenna electronics inside the vehicle. Users can select from a variety of 4-element
CRPA antenna arrays.
How it works
GAJT-AE-R mitigates interference by creating nulls in the antenna gain pattern in the direction of the jammers, providing significant anti-jam protection even in dynamic multi-jammer environments. The output is a protected standard Radio Frequency (RF) signal, free from jamming and suitable for input into modern and
legacy GNSS receivers.
Leading-edge technology
Interference mitigation is achieved by applying proprietary digital null forming algorithms to the signals, creating dynamic nulls to give protection against narrowband and broadband interference sources. The unit comprises Radio
Frequency (RF) front ends and null forming electronics. Integration to your GNSS receiver is seamless; DC power supply and data output are via separate connectors.
Protects GNSS navigation and precise timing receivers GAJT-AE-R protects GPS L1/L2, QZSS L1/L2, SBAS L1 and Galileo E1 signals. The wide bandwidth of GAJT ensures compatibility with M-Code GPS.
