The TUALAJ 4200 MINI GPS/GNSS anti-jamming system is designed to sustain reliable GNSS operation in contested electromagnetic environments. Based on a 4-array CRPA and advanced beamforming techniques, the system suppresses multiple interference sources to ensure continuous GNSS receiver functionality during critical operations.
Separate anti-jamming channels enable simultaneous operation across GPS L1/L2 or GPS L1/GLONASS L1 configurations. The system also supports Galileo E1, Beidou B1, and SBAS signals, with wide channel bandwidths allowing compatibility with M-Code and SBAS signals. This multi-constellation support enhances PNT performance in complex signal environments.
Engineered for deployment across land, maritime, and air-based defense platforms, as well as fixed installations, the system is compatible with both civil and military GPS receivers. Its compact form factor, flexible antenna options, and wide operating voltage range support efficient integration into both new and existing systems.
Manufactured to meet MIL-STD environmental and EMI/EMC requirements, the TUALAJ 4200 MINI is suited to demanding operational conditions, delivering assured PNT performance across a broad range of tactical applications.
