SAJ protects an unmanned maritime vehicle against jammers
The patent-pending SAJ anti-jam shield was integrated on an unmanned sea vehicle for the first time — with successful field results under intense jamming.

Sağlamtek’s patent-pending anti-jam shield SAJ was recently integrated on an unmanned maritime vehicle (UMV) and delivered very successful results.
From UAVs to the sea
SAJ had already proven itself in many integrations on drones and UAVs; this was the first time it was fitted to an unmanned maritime vehicle.
Field test under jamming
The UMV manufacturer has been actively testing the SAJ-0B1 model in the field, and the results have been highly positive. Despite challenging conditions with intense interference and jamming, SAJ performed successfully.
The customer appreciated Sağlamtek’s advancements and stated that they look forward to continued success with the technology.
How SAJ works
SAJ is a passive shield mounted around an existing standard or CRPA GNSS antenna. It rejects interference arriving from low elevation angles — where ground and sea-level jammers usually are — while the antenna keeps its view of the sky. The housing is mechanically adapted to each platform.
