Anti-Jamming 
|
In regions such as the Baltic Sea, where GNSS interference and spoofing are becoming increasingly common, reliable navigation is critical. NT-GNSS-AJ is an advanced system with active anti-jamming protection, designed for all types of vessels. Thanks to its multi-constellation GNSS receiver, specialized antenna, and NMEA 0183 integration, the system provides stable and trustworthy navigation data—even as a backup GNSS solution. It is also available as a complete turnkey installation.

APPLICATION EXAMPLE
|
Thanks to the use of an interference-resistant antenna and a multi-band GNSS receiver, the system effectively protects against jamming and spoofing, ensuring stable and reliable navigation data even in demanding conditions. The NMEA communication standard enables seamless integration with equipment such as ECDIS, AIS, and VDR, while the wide power supply range (12–24 VDC) allows for easy installation on various types of vessels. |
