Accurate location information is crucial for many military and commercial applications. Global Navigation Satellite Systems (GNSS) are used extensively in land applications within manned and unmanned vehicles, guided munitions, and many other platforms all around the world. The power level of the GNSS satellite signals on earth is well below the noise floor, which makes those signals vulnerable to RF interference. Military operations in recent years have shown that many platforms used in the tactical field are under a clear threat of GPS/GNSS jamming and spoofing.

CRPA Technology is the ANSWER

Controlled Reception Pattern Antennas (CRPA) have the capability of providing electronic protection to GNSS receivers against RF interference including jamming and spoofing. They exploit the idea of beamforming and are based on the principle that interference could be suppressed via specially designed antenna array with digital beamforming.

TUALAJ Anti Jamming GNSS: Best Performance, Compact Dimension and Lightweight

TUALCOM’s TUALAJ anti-jamming CRPA product family uses a proprietary electronic protection technology developed for GPS/GNSS systems with lessons learned from the tactical field. This technique is realized fully digitally and is based on detecting the jamming signals instantaneously and preventing the jamming signal from entering the GPS/GNSS RF chain at the antenna level.

TUALCOM has developed a wide spectrum of Anti-Jamming CRPA products providing an effective solution against a multitude of GPS/GNSS jamming and spoofing threats. The most prominent features of TUALAJ Anti-Jamming GNSS product family are,

  • Ability to work with multiple constellations – TUALAJ products can provide electronic protection for GPS (L1, L2), GLONASS (G1, G2), Galileo (E1), and BeiDou (B1) signals and anti-jamming can be performed on a combination of up to three different bands simultaneously.           
  • Ultra-Low SWaP - For platforms with space limitations, TUALCOM provides the smallest, lightest, and fully performing solutions in the TUALAJ Anti-Jam product family. Integrating Digital Control Antenna Unit (DACU) with CRPA Array offers many SWaP advantages.
  • Product Diversity – TUALCOM offers a wide range of solutions for different platforms and various field requirements.  TUALAJ family products come with different form factors and antenna options with 4 and 8 antenna array models that can provide jamming cancellation up to seven jamming sources.  
  • Easy integration – TUALAJ products can easily be integrated into platforms via a digital connector and RF cables between the antenna array and DACU.
  • Embedded GNSS receiver option – Although TUALAJ products could be used together with existing GNSS receivers, there is also an internally integrated GNSS receiver option ideal for applications with space and power limitations. 

TUALAJ 4200 MINI: Compact Dimension and Lightweight

Among five main commercial-off-the-shelf (COTS) product line and more than tens of different possible configurations, TUALAJ 4200 MINI is the smallest member of the family. The DACU weighs less than 170 gr (6 ounces). It provides interference cancellation for up to 3 simultaneous independent jammers and on two selected GNSS bands.
