Hexagon | NovAtel has released the GAJT-410MS in response to the increase of interference and jamming in marine environments worldwide. The GAJT-410MS is the company’s latest addition to its proven GPS Anti-Jam Technology (GAJT) for the commercial and defense marine markets.

The low size, weight and power (SWaP) variant protects civil and military operations from interference and jamming, with jammer direction-finding capabilities for enhanced situational awareness in the marine environment.

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.

The commercial off-the-shelf, non-ITAR solution is easy to install or retrofit onto existing fleets, enabling assured PNT for continuous operations, cybersecurity and safe navigation at sea, NovAtel said.

Interference, both benign and malicious, is a challenge facing civilian and military operations. Commercial marine applications like shipping, tankers and bulk carriers are under threat from interference targeting their navigation and cybersecurity. Without assured positioning, these vessels can drift off-course and place the vessel, crew and cargo at risk.

Nearshore marine applications like survey, construction and piloting also require reliable positioning for uninterrupted operations in crowded waterways and RF environments. Interference mitigation and jammer direction-finding for advanced situation awareness ensure users acquire assured positioning, navigating and timing (PNT) while identifying and limiting risk from interference sources.

“Assured navigation and cybersecurity defenses are growing priorities for marine users as global threats from interference and jamming increase,” said David Russell, marine segment portfolio manager for Hexagon’s Autonomy & Positioning division. “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.”

The GAJT-410MS is the latest iteration of proven, high-performance anti-jam products from NovAtel. It includes flexible mounting options, jammer presence and direction-finding capabilities for advanced situation awareness.
