Product overview
The TX04 integrates an eight-element antenna array into an off-the-shelf navigation protection unit. Its structure supports convenient installation, with a 160 × 160 × 35 mm envelope and a weight of 770 g. The antenna arrangement is specified as 4 + 4. Integration provisions include a serial data interface, one SMA female connector and a J30J 21-pin socket. The unit requires 12 VDC and consumes less than 25 W, defining its electrical requirements for installation on a host platform.
Interference suppression works by forming nulls toward incoming jammers, while the output remains a protected standard RF signal for a GNSS receiver. Protected frequencies are GPS L1 and L2, GALILEO E1 and BEIDOU B1, with an interference-source count of 3 on L1 plus 3 on L2. The greater than 95 dB J/S performance figure applies to a typical GPS receiver with three broadband jammers from different directions. Operating temperature spans -40 °C to +70 °C. Applications include fixed-wing aircraft, rotorcraft, unmanned aircraft systems, armored vehicles, ships and fixed installations.
