With full multi-constellation, multi-frequency GNSS signal protection, the GAJT-AE3 provides assured positioning, navigation and timing (PNT)
Hexagon | NovAtel has launched the latest addition to its battle-proven GNSS Anti-jam Antenna Technology (GAJT) lineup: GAJT-AE3. The GAJT-AE3 emerges in response to the escalating power and sophistication of jamming techniques that disrupt satellite-based navigation systems, a concern highlighted by current worldwide geopolitical conflicts.
As jammers become more powerful and low cost, with the capability of targeting a wider range of GNSS frequencies, there is a critical need for next-generation functionality and reliability.
To address this, the GAJT-AE3 protects all major GNSS constellations with full multi-constellation, multi-frequency coverage. This significant advancement in jamming protection — in a compact format — ensures reliable PNT in demanding airborne environments.
“This is a revolutionary expansion in our battle-proven anti-jam solutions designed specifically for space-constrained platforms,” said Stig Pedersen, president, Aerospace & Defence Division, Hexagon. “The GAJT-AE3 offers unparalleled signal coverage and multi-jammer direction finding for superior protection and heightened situational awareness.”
The GAJT-AE3’s antenna electronics mitigate interference by creating up to seven nulls per band in the direction of jammers, providing significant anti-jam protection even in dynamic multi-jammer scenarios. The output is a protected radio frequency signal, free from jamming and suitable for input to modern and legacy GNSS receivers.
Protecting and supporting all GNSS frequencies, including L-band corrections and Iridium PNT, the GAJT-AE3 is an easy-to-integrate, compact unit suitable for use on a variety of platforms, from UAVs to complex weapons. It can be paired with a range of antennas from the Hexagon | Antcom portfolio, including custom options.
Hexagon | NovAtel’s GAJT-AE3 is now commercially available.
