GNSS Anti-Jamming Solutions
SAGLAMTEK’s GNSS anti-jamming portfolio protects mission-critical PNT (positioning, navigation and timing) against jamming, spoofing and multipath interference. The range includes compact CRPA systems, integrated receiver-antenna units, passive shielding and GNSS repeaters for secure and enclosed facilities.
BORAJ-V16 Single-Band GNSS CRPA System
Single-Band L1 Anti-Jamming GNSS CRPA System
BORAJ-V16 is a rugged, 16-element Controlled Reception Pattern Antenna (CRPA) system designed to protect positioning, navigation, and timing in contested RF environments.
Adaptive null steering and advanced interference suppression deliver reliable GNSS performance for airborne, ground, and maritime platforms.
BORAJ-V8 Dual-Band GNSS CRPA System

High-level protection against multiple GNSS interference sources
BORAJ-V8 combines an eight-element dual-band array with advanced signal processing for greater resilience against multiple sources of GNSS interference. Used with the SAJ GNSS Shield, it delivers more than 100 dB of unwanted-signal suppression and provides protected NMEA 0183 navigation data through a customizable Micro-D interface.
BORAJ-SLIM4 Dual-Band GNSS CRPA System
Low-profile dual-band protection for defense platforms
BORAJ-SLIM4 combines a four-element antenna array with dual-band anti-jamming and anti-spoofing capabilities in a low-profile, IP67-rated enclosure. The Pixhawk-compatible system provides NMEA 0183 communications through a customizable Micro-D interface, allowing straightforward integration into compact platform navigation architectures.
BORAJ-MINI4 GNSS CRPA System
Four-element CRPA for PNT protection against jamming and spoofing
BORAJ-MINI4 is a compact four-element CRPA system designed to preserve mission-critical PNT in the presence of GNSS jamming and spoofing. Covering L1, B1 and E1 frequencies together with either L2 or L5, it delivers up to 95 dB of unwanted-signal suppression when combined with the SAJ GNSS Shield.
SAJ GNSS Shield
Field-proven anti-jam shielding for existing military GNSS antennas
SAJ is a battle-proven passive shield installed around an existing conventional or CRPA GNSS antenna to attenuate jammer and multipath signals arriving from 90 degrees and above. Each unit is mechanically adapted to the host platform and delivers 20 to 30 dB of unwanted-signal suppression. It has been selected by multiple domestic and international drone manufacturers and military institutions, and is currently deployed in field operations.
GNSS Repeater / Anti-Jam GNSS Repeater
Reliable GNSS coverage inside hangars and enclosed facilities
The SAGLAMTEK GNSS Repeater receives live satellite navigation signals through an outdoor antenna and reliably retransmits them inside military aircraft hangars and other enclosed facilities where structural materials prevent normal GNSS reception.
Under a contract with the Turkish Ministry of National Defence, SAGLAMTEK is deploying GNSS Repeater systems at military aircraft hangar facilities across Türkiye. The systems support indoor testing, maintenance and verification of aircraft avionics and GNSS-dependent equipment without requiring the aircraft or platform to be moved outside.
This capability reduces maintenance and test time while eliminating delays associated with GNSS signal acquisition and navigation-system initialization. The system can also support UAVs, robotic platforms and other GNSS-equipped vehicles undergoing testing inside enclosed facilities.
An Anti-Jam GNSS Repeater configuration is also available for facilities operating in challenging electromagnetic environments, providing resilient indoor GNSS signal distribution by reducing the impact of external interference and jamming.
