Since the Global Navigation Satellite System (GNSS) signals go a long way until they reach the receiver, they are weakening in terms of power due to atmospheric effects. This situation causes the Global Navigation Satellite System signals to be easily suppressed by various jammers, the receiver to lose the signal tracking and start not producing solutions. The jamming of the Global Navigation Satellite System, which are available on many of platforms, by enemy elements causes great problems including the platforms losing their function or even crash.   

It is critical to clear and suppress jammer signals for the survival of our military platforms. In this context, Meteksan Defence has completed the development of the Anti-Jamming GNSS (Anti-Jamming/Deception GNSS System) product that supports GPS, GLONASS, GALILEO, BEIDOU satellite signals and can work on multiple frequency bands. Thanks to the Meteksan Defence Anti-Jamming GNSS product, direction of the jamming signal can be determined and suppression of the jamming signals is achieved by using spatial filtering. Jamming signals are filtered by using signal processing techniques, and the original signal without the jamming signal is reconstructed again for delivering to standard GNSS receivers.

Meteksan Defence Anti-Jam GNSS also includes a built-in GNSS receiver capable of decoding GPS satellite signals for calculating position, velocity and time information. This way, without needing an external GNSS receiver, Meteksan Defence Anti-Jam GNSS can both output filtered GNSS RF signal and calculate position/velocity/time information from the filtered signal. Thanks to the high-tech antenna design infrastructure owned by Meteksan Defence, it also develops their own CRPA antenna designs and offers a variety of antenna specific to the platforms.

The Anti-Jamming GNSS, which has been developed by Meteksan Defence, stands out from its counterparts as a product that contains world-class technologies against jamming threats that we may encounter in the combat environment, which can be used on all types of platforms, primarily missile systems and Unmanned Aerial Vehicles thanks to its dimensions and lightness.

Meteksan Defence President Selçuk Alparslan states that the Anti-Jamming GNSS is one of the examples of Meteksan Defence’s proactive product development approach: “The high-tech electronic systems we have developed for our many military platforms such as helicopters, unmanned aerial vehicles, missile systems have created a very serious accumulation in terms of human resources, technology, infrastructure and business ecosystem at Meteksan Defence. We transfer this accumulation to other areas that we consider required, without waiting for it to be a project, using our own resources. The Anti-Jamming GNSS is also a product of this approach. We are confident that this new system will make an important contribution to the reliability and security of the platforms of our Turkish Armed Forces.”

The main technical specifications of the Anti-Jamming GNSS include:

  • Ability to work on GPS L1, GPS L2 and GLONASS L1 frequency bands
  • 4 array antenna (CRPA)
  • Platform-specific antenna design
  • Resistance against more than one jammer signals
  • Ability to work at high speed, dynamic and high altitudes
  • Low power consumption, lightweight and compact
  • Built-in Receiver
  • MIL-STD-810G and MIL-STD-461F compliant


Meteksan Defence has been established in 2006 in order to combine and coordinate the projects and activities of the high technology companies operating within the body of Bilkent Holding for the defense and aviation industry under a single roof. In the defense and aviation sector, in line with the vision put forward by Presidency of Defence Industries, it continues its works to develop high-tech, independent and unique products and subsystems for the Turkish Armed Forces.

Meteksan Defence, who operates in 6 main fields including radar systems, perimeter surveillance systems, laser and electro-optic systems, communication systems, underwater acoustics systems and platform simulators, is involved platform projects of Turkey, such as ships, helicopter, drone, and many critical projects such as the development of anti-tank and air defense missile systems. Radar and ladar systems, perimeter surveillance radars, altimeters, tactical and strategic missile systems data links, sonar systems, underwater early warning and communication systems and training simulators for helicopters and UAVs are the main original and national products developed by Meteksan Defence.
