Application domains
Built for every domain that depends on a signal.
From fixed-wing aircraft to unmanned surface vessels — our systems protect position, navigation, timing and the data link.
Capabilities
Mission-critical RF, navigation and control systems.
Each product family is designed, manufactured and tested in Ankara — and can be adapted to your platform’s frequency plan, interfaces and mechanical envelope.
How anti-jam works
Steer a null at the jammer. Keep the satellites.
GNSS signals arrive at the antenna weaker than the receiver’s own noise floor, so even a low-power jammer can erase them. A CRPA array solves this spatially: it shapes its reception pattern in real time so the jammer’s direction goes deaf while the sky stays visible.
- 01
Sense
Each CRPA element samples the RF environment independently.
- 02
Null
Adaptive weights steer deep nulls toward each interference source.
- 03
Protect
Clean satellite signals reach the receiver; spoofing is flagged.
Reception pattern
4-element CRPA
- Satellites · tracked
- Jammer · nulled
- Gain pattern
Custom design
Empower your business with high-precision engineering.
When an off-the-shelf part doesn’t fit the frequency, the envelope or the platform, our design team builds one that does — from the first simulation to the qualified unit.
- RF, PCB and antenna design in one team
- Designed to your frequency, size and environment
- Mechanics adapted to your platform
RF Design
Active and passive RF components — amplifiers, filters, front ends — designed to your link budget.
PCB Design
Single-layer to multi-layer boards with RF-aware stack-ups, routing and EMC practice.
Antenna Design
Antennas tailored to frequency, pattern, size and environmental requirements.
Platform Integration
Mechanical and structural adaptation so the hardware fits your airframe, hull or vehicle.
Field reference
Live GNSS inside F-16 and F-4 hangars.
Aircraft parked in a hangar lose satellite reception, so avionics checks used to mean towing the aircraft outside. In collaboration with the Presidency of Defence Industries (SSB) and the Turkish Air Force, Sağlamtek GNSS repeaters bring live satellite signals into closed hangars — crews now test navigation systems in place. The system is codified under NSN 5895-27-0716789.

Go to the contact form01What is a GNSS anti-jam system?
A GNSS anti-jam system keeps a receiver locked on satellite signals when an interference source tries to drown them out. Sağlamtek’s BORAJ systems use a CRPA antenna array and adaptive processing to suppress jamming and detect spoofing, so the platform keeps its position, navigation and timing.
02How does a CRPA antenna work?
A Controlled Reception Pattern Antenna (CRPA) combines several antenna elements. By weighting the signal of each element, the processor places a “null” — a deep drop in sensitivity — in the direction of the jammer while still receiving satellites from other directions. More elements allow more jammers to be nulled at once.
03Can I add anti-jam protection to an antenna I already use?
Yes. The SAJ GNSS Shield is a passive shield mounted around an existing standard or CRPA antenna. It adds 20–30 dB of rejection against interference arriving from 90° and below, and the housing is mechanically adapted to each platform.
04What is the difference between telemetry and a data link?
Telemetry is the flow of flight and status data from a vehicle to the ground. A data link is the radio channel that carries it — and, in products such as BORLINK-0821, also carries HD video, serial data and commands in both directions over encrypted IP.
05Do you design custom antennas and RF hardware?
Yes. Our engineering team designs active and passive RF components, single- to multi-layer PCBs and antennas to your frequency, size and environmental requirements, and adapts the mechanics to your platform.
06Which platforms use Sağlamtek products?
Our products serve air, land and sea platforms — from UAVs and helicopters to armoured vehicles and vessels — and are used by platform manufacturers, system integrators and operators in more than 10 countries.
