The TUALAJ 8300 CRPA GNSS anti-jamming system is designed to deliver reliable GNSS performance in heavily contested RF environments. Based on an 8-element CRPA, combined with an advanced digital controller and proprietary beamforming algorithms, the system suppresses interference from up to seven directions across three frequency bands, maintaining continuous GNSS receiver operation during mission-critical activities.
The protected frequency set can be selected from available configuration options, allowing the system to be tailored to specific operational requirements. Additional protection is provided through adaptive notch filtering and pulse blanking, further improving resilience against complex interference sources.
An optional embedded GNSS receiver supports SBAS signals, enhancing positioning accuracy and reliability where required. The system is compatible with both civil and military GNSS receivers and supports integration across land, maritime, and air-based defense platforms, as well as fixed installations.
Two CRPA antenna configurations are available to meet size and weight constraints, enabling deployment across a range of platform types. Designed for straightforward integration with both new and legacy systems, the TUALAJ 8300 supports a wide range of tactical operations where assured PNT is required. Built to MIL-STD-810G and MIL-STD-461F standards, it ensures dependable performance in demanding operational environments.
