The GAJT-410MS antenna utilizes CRPA technology and null-forming electronics to mitigate threats to position, navigation and timing (PNT) availability such as jamming, spoofing and unintentional interference. Compatible with legacy and modern GNSS receivers, it provides dynamic protection of M-Code signals as well as GPS L1 and L2, Galileo E1, QZSS L1 and L2, and SBAS L1.
Built-in adaptive digital null-forming algorithms identify interference and jamming signals, adjusting the gain on reliable satellite signals to maintain PNT. Powerful direction-finding capabilities enable you to identify and locate the source of jamming signals, and optimize awareness of your RF environment.
The low-SWaP GAJT-410MS is ideal for space-constrained military, commercial and uncrewed vessels, and features a marine-hardened enclosure for reliable operation in harsh conditions.
