Hexagon | NovAtel has released a new GPS Anti-Jam Technology (GAJT) solution aimed at commercial and defense marine markets. The GAJT-410MS is a low-SWaP (size, weight and power) unit that protects platforms such as unmanned surface vessels (USVs) from interference and jamming, with jammer direction-finding capabilities for enhanced situation awareness in the marine environment.
Both benign and malicious interference can affect civilian and military operations. Commercial marine applications such as shipping are under threat from interference that targets their navigation and cybersecurity. Without assured positioning, these vessels can drift off-course. Nearshore marine applications such as surveying and construction require reliable positioning for uninterrupted operations in crowded waterways and RF environments, and an interference mitigation and jammer direction-finding solution such as the GAJT-410MS ensures that users can acquire assured positioning, navigating and timing (PNT) while identifying and limiting risk from interference sources.
The GAJT-410MS provides dynamic protection on both GPS L1 and L2 bands, as well as Galileo E1, QZSS L1 and L2 and SBAS L1, to combat intentional and unintentional interference. If a vessel experiences jamming, the device’s direction-finding capabilities provide improved situation awareness of their RF environment to identify and locate the source of the jamming signals. This commercial off-the-shelf, non-ITAR solution is easy to install or retrofit onto existing USV fleets, enabling assured PNT for continuous operations, cybersecurity and safe navigation at sea.
Dr. David Russell, marine segment portfolio manager for Hexagon’s Autonomy & Positioning division, commented: “Assured navigation and cybersecurity defenses are growing priorities for marine users as global threats from interference and jamming increase. The GAJT-410MS is an anti-jam solution protecting vessels from interference and jamming disruptions to ensure continuous operations wherever your application takes you. With GAJT, your position, navigation and timing are protected and assured.”
