Hexagon | NovAtel, a global technology leader, launched the latest addition to its trusted, 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.

With full multi-constellation, multi-frequency (MCMF) GNSS signal protection, the GAJT-AE3 provides best-in-class assured positioning, navigation, and timing

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 is the first anti-jam product to protect all major GNSS constellations with full multi-constellation, multi-frequency (MCMF) coverage. This significant advancement in jamming protection – in a compact format – ensures reliable positioning, navigation, and timing (PNT) in the most demanding airborne environments.

“This is a revolutionary expansion in our battle-proven anti-jam solutions designed specifically for space-constrained platforms,” stated 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 customer
