Gatekeeper offers surround vision for close-in situational awareness up to a distance of 5-8 km, to as close as 15 m from the ship, for safe navigation and against asymmetric tactics such as piracy, insurgency and swarm engagements.
Gatekeeper is a 360°electro-optical surveillance suite comprising, non-cooled IR cameras and ultra high definition TV cameras mounted in the mast, to provide a continuous un-blocked situational awareness for multiple operating positions. Its main role is to provide security through classification and identification of approaching objects, and target indication to remote controlled small arms. In addition, the system will provide recording of events in order to have legal evidence.
It provides 24-hour, day/night surveillance allowing the crew to be deployed more efficiently with personnel being able to stay inside a protected, air-conditioned environment rather than having to stand watch on deck. Gatekeeper also allows the ship to have a relaxed alert state and still be able to respond quickly in case of an emerging threat, Gatekeeper excels in harbours and confined waterways where radar use is restricted and radar performance is limited.
A Gatekeeper system will have up to 4 sensor units, each comprising 3 non-cooled IR and 3 TV cameras with a combined view of 120°in azimuth. If mounting positions allow, they are integrated into a seamless 360° view, otherwise a number of segments is presented.
The algorithms for seamless automatic target detection, tracking and alert of asymmetric tactics are a refinement of the proven algorithms as developed for Irscan, Sirius and Mirador.
The 360°surveillance image is available for multiple operator stations, where each operator has his own 'software controlled window' for amplification of track data and zoom-in without disturbing the 360°view for other users at the bridge, operations room or watch stand.
The panoramic view can also be displayed on large screen('s) in the combat information centre.
Gatekeeper is also available as a stand-alone upgrade for naval ships or other applications, such as oil rigs at sea or land-based bases and compounds to offer protection against asymmetric threats and piracy.
