Jamming and interference in marine environments are growing worldwide threats for both civilian and military operations. These activities threaten the continuous operation of nearshore applications like hydrographic survey, marine construction, dredging and piloting. Interference, jamming and spoofing threatens commercial shipping vessels like tankers and bulk carriers by targeting their navigation and cybersecurity.
Whether the interference is malicious or benign, these activities put the vessel, crew and cargo at risk. For nearshore vessels, continuous positioning, navigation and timing (PNT) is necessary for safe operations in crowded waterways and RF environments. Commercial vessels may drift off-course without assured PNT and run the risk of shipping delays or navigation into unsafe waters.
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 and L2, Galileo E1, QZSS L1 and 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 of your RF environment.How it works
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.Features
