Anti-jam Antenna Systems (GAJT)

In an environment with few to no landmarks, interference like jamming and spoofing has only increased in recent years and is a major threat to safe positioning, navigation and timing . Vessels rely on instruments for their location and orientation; when they can no longer deliver accurate measurements, crew and cargo are at risk.

When experiencing interference, marine operations experience downtime, cargo may be lost and crew endangered. Jamming and spoofing protection are a key aspect to building a reliable and assured positioning solution.

GPS Anti-Jam Technology (GAJT) protects the satellite signals that generate the positioning measurements, empowering vessels to trust their position, navigational route, and timing synchronisation.
