    Hexagon | NovAtel has updated its GPS Anti-Jam Technology (GAJT) portfolio with the new GAJT-710 product line, which features several enhancements over the previous generation.

    The GAJT-710 product line is the next evolution of NovAtel’s battle-proven anti-jam technology for land and marine platforms. The new jammer direction-finding capability of GAJT enables situational awareness and a new silent mode feature reduces its thermal signature. These improvements, including enhanced GNSS tracking performance, are achieved while maintaining the same form and fit of the previous generation product.

    GAJT units are deployed worldwide, providing anti-jam protection on land, at sea and in the air. Across these environments, GAJT protects GNSS navigation and precise timing receivers from the growing threats of intentional jamming and unintentional interference. GAJT reliably provides APNT for allied forces no matter the scenario.

    “NovAtel has proven itself as a leader for assured PNT through our GAJT portfolio,” said Steve Duncombe, executive vice president of aerospace and defense at Hexagon’s Autonomy & Positioning division. “The new GAJT-710 builds on that success by providing new features combined with existing mission-proven technology to continue providing evolutionary APNT capabilities for the warfighter, national infrastructure and other mission-critical applications.”

    NovAtel’s commitment to APNT is central to its product design approach. Deep GNSS expertise and lean manufacturing capabilities enable the delivery of high-performance products like the GAJT-710 in large volumes with minimal production and delivery times, the company said.

    The GAJT-710 product line is available for land vehicles, marine vessels, positioning networks and timing infrastructure.

    GPS World celebrates its 30th anniversary, and together we’ve seen huge leaps of innovation over the years. Reflecting on these developments, I wanted to share some of the contributions Hexagon | NovAtel made to support the evolution of the GNSS industry.

    We began in 1978 in Alberta, Canada, in the telecommunications industry. In the 1990s, we shifted our focus to satellite receivers, choosing to forge ahead in GPS/GNSS technology. This decision would see NovAtel become one of the world’s leading manufacturers of high-precision GNSS components and systems developing multiple new patents and innovative solutions.

    Our engineers have seen first-hand the growth of GPS and other satellite positioning systems worldwide, GNSS adoption across industries from aerospace to agriculture, and the present-day developments of precise positioning in autonomous applications. A rising tide raises all boats, and we helped foster the evolution of the industry through our goals of assured autonomy and positioning.

    Assured positioning means a reliable and robust solution you can trust. Technologies we’ve contributed to the broader industry include our GPS Anti-Jam Technology (GAJT) protecting users’ positioning, time and navigation, and SPAN technology, which expertly combines GNSS and inertial navigation systems (INS) measurements for seamless motion observations and a robust positioning solution. The capabilities of these technologies have been major contributors to the evolution of the GNSS industry.

    Hexagon acquired NovAtel in 2007, and we’ve continued to grow and develop exciting new opportunities around the world where GNSS can grow, strengthen and improve applications in agriculture, automotive, defense, marine and many other industries. Our mission of assured autonomy and positioning encourages us to continue providing assured positioning in the most demanding environments and begin bringing autonomy to these markets.

    GPS World has been a key player in covering these technological advancements for the past three decades. Together as an industry, we’ll continue innovating positioning and autonomy, and I’m excited to see how the industry will evolve over the next 30 years.

    NovAtel’s GPS anti-jam technology chosen for UK’s Type 26 frigate

    NovAtel’s GPS Anti-Jam Technology (GAJT) has been selected for the United Kingdom’s Type 26 frigates to meet a requirement as part of a protected navigation system.

    The frigates are 21st-century warships that will replace the Type 23 frigate as the workhorse of the British Fleet, undertaking the Royal Navy’s three core roles — warfighting, maritime security and international engagement — on the world stage.

    GAJT protects GPS-based navigation and precise timing receivers from intentional jamming and accidental interference, ensuring that the satellite signals necessary to compute position and time are always available. It is a commercial off-the-shelf (COTS) product, and comes in versions suitable for land, sea, fixed installations and smaller platforms such as unmanned aerial vehicles (UAVs).

    Warships, military vehicles and platforms, networks and timing infrastructure can all benefit from the protection that GAJT provides. There is no need to replace GPS receivers already installed, because GAJT works with civil and military receivers including SAASM and M-code.

    “The selection of GAJT for the Type 26 frigates is the result of cooperation between Drumgrange, with its proven track record for rapid realisation of demanding defence design tasks, and Forsberg Services, an established navigation systems company and NovAtel dealer whose high quality manufacturing was instrumental to the project,” said Peter Soar, business development manager for military and defence at NovAtel. “GAJT is in use operationally and has been shipped to 16 allied nations around the globe. We are grateful for the rigorous technology selection process conducted which led to this choice.”

    NovAtel’s commitment to precise, assured positioning and timing is central to the design of the GAJT antenna. The company’s lean manufacturing techniques and quality processes mean that it can ramp up quickly to meet volume requirements. Reliability is assured by NovAtel’s industry-best low return rate.
