The GAJT-410MS protects your crew, vessel and cargo from interference, jamming and spoofing through dynamic protection on M-Code signals as well as GPS L1/L2, Galileo E1, QZSS L1/L2 and SBAS L1. GAJT uses an adaptive digital null-forming algorithm to identify interference and jamming signals, adjusting its gain on reliable satellite signals to maintain your PNT. Its direction-finding capabilities enable you to identify and locate the source of jamming signals and optimize situation awareness.
Designed specifically for rapid integration into space-constrained vessels, this easy-to-use system protects GPS-based navigation and precise timing receivers, including M-Code, from both intentional jamming and accidental interference.
How it works
GPS Anti-Jam Technology (GAJT) mitigates interference and jamming by creating nulls in the antenna gain pattern in the direction of jammers. This process enables advanced anti-jam protection even in dynamic multi-jam scenarios. Whether intentional or unintentional interference, GAJT identifies and mitigates the threat to your PNT.
