Accurate position information is crucial for many military and commercial applications. Global Navigation Satellite Systems is the most common source for position in land, airborne and marine applications within manned and unmanned vehicles, guided munitions, and many other platforms 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 intentional or unintentional 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.
TUALCOM is dedicated to provide resilience to systems/platforms with GNSS against jamming. R&D-driven design and development processes have led to the most advanced AntiJam solutions and the most diverse product family for all kinds of requirements and platforms.
CRPA Technology and Beyond
Superior in-house engineering capabilities have helped develop a state-of-the-art digital antenna control unit (DACU) to elevate the commonly used Controlled Reception Pattern Antenna (CRPA) technology for jamming suppression to another level. The proprietary DACU is easily configured to control beams of 2, 4 or 8 antennas to allow the world’s most versatile and diverse antijam product family to be offered off-the-shelf, conforming to all size, weight, power and cost requirements.
At TUALCOM we prefer to call our products Customized-Off-The-Shelf (C-OTS) to indicate our commitment and ability to provide tailor made solutions to our customers’ needs should the selected off-the-shelf product is not 100% match to the needs. The most prominent features of TUALAJ Anti-Jamming GNSS product family are,
- Ability to work with multiple constellations – TUALAJ family has the ability to work with multiple constellations and depending on the selected product, protection for up to three different GNSS bands, namely, GPS (L1, L2), GLONASS (G1, G2), Galileo (E1), and BeiDou (B1) simultaneously, is provided.
- Ultra-Low SWaP - For platforms with space limitations, TUALCOM provides the smallest, lightest, and fully performing jam-free solutions. While the integrated DACU-CRPA structure helps achieving Ultra-Low SWaP features, the performance is never compromised providing resilience against up to 7 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 the strictest space and power limitations.
With these features, TUALCOM’s GNSS AntiJam systems have been deployed on more than 10 different maritime and air platforms and their performance has been improved with lessons learned from the tactical field. This is the main reason TUALCOM has sold more than 3,000 AntiJam Systems within the last 12 months worldwide.

The science of soldier safety: How Team Wendy Is reinventing the modern military helmet
When soldiers head into the field, the helmet on their head can mean the difference between life and death. But while helmets may look simple from the outside, the technology inside them is anything but. Few companies illustrate this better than Team Wendy, whose newest bump helmet — the RECON™ Tactical — shows just how far modern head protection has come.
