HGPST4 anti-jam with directional control

The use of the GPS Anti-Jam Landshield antenna eliminates the jamming effect by self-adaptation of the reception characteristics of the antenna (the so-called zero control). This eliminates unwanted signals while maintaining the continuity of signal reception from other directions.

The HGPST4 ANTI-Jam system is offered to the Armed Forces' use in combat units requiring special battlefield protection, including radars, command vehicles, communication nodes, and fire control units.

The HGPST4 receiver complies with the Polish Defense Standards.


Hertz Systems - a Polish manufacturer and supplier of military GPS receivers equipped with a cryptographic module. The Polish Armed Forces are one of the recipients of the system. The HGPST-UAV receiver allows for using the American military navigation signal (SAASM cryptographic module); it has adapted interfaces and signals to be compatible with devices mounted on unmanned platforms flying.

The HGPST UAV with the SAASM module can receive and decode the C/A and P (Y) signals on the frequencies (L1, L2) transmitted by the GPS system. The receiver works in PPS (Precise Positing Service) mode, which gives full access to military GPS frequency and maintains accurate time and position indication in the event of jamming or spoofing.

HAWK system

The Hawk system is an autonomous anti-drone system designed to protect objects against unmanned aerial systems - UAVs of various classes and commercial drones, including drones that do not transmit any radio signals and fly autonomously in accordance with a programmed mission. Protection by detecting, identifying, tracking and counteracting/neutralizing with the use of a multisensory system of recognition, interference and control take over.

The HAWK anti-drone system is available in 3 variants:

  • on-site version
  • mobile version
  • handheld neutralizer
