Canadian company CMC Electronics has teamed up with Swedish firm Hexagon to protect aircraft from jamming and spoofing attacks on GNSS positioning technology.

Hexagon’s autonomy and positioning division, which includes the NovAtel brand, has developed a multi-constellation, multi-frequency (MCMF) GNSS platform. Merging CMC’s certification expertise with digital signal processing from NovAtel, this MCMF GNSS platform focuses on detection of spoofing and jamming, lighter weight and a smaller form factor.

GNSS signals underpin the safety and reliability of all aviation. Jamming and spoofing of GNSS signals is no longer confined to military conflicts; users in the commercial realm are being affected all over the world. As the aviation industry embraces the era of MCMF GNSS positioning and assured positioning, navigation and timing (APNT), CMC and Hexagon say they are ready to deliver for the commercial aviation, military and unmanned aerial systems markets.

“Our partnership with NovAtel has been a long-lasting, collaborative and mutually supportive relationship and, together, we are not just advancing but pioneering the future of aviation GNSS technology,” said Nick Chalkiadakis, CMC business unit director. “As leaders in the industry, we are setting a new standard of excellence by introducing a new era of high-precision, high-performance GNSS to the market.”

CMC’s receiver, certified to the DO-254 level A standards, seamlessly integrates GNSS measurement technology from Hexagon.

“We have been working on and delivering safety-critical positioning technology for 25 years, since the field’s inception, and much of that work has been side-by-side with CMC,” said Stig Pedersen, Hexagon executive vice president. “We’re thrilled to provide our expertise to partners advancing the future of their industries, empowering them with best-in-class positioning technology.”

CMC Electronics (cmcelectronics.ca) has a reputation for innovation in the design and manufacture of cockpit systems integration, avionics, displays and microelectronics for the military and commercial aviation markets. Based in Montreal, Canada, the company has facilities in the USA serving its customers worldwide.

Stockholm-based Hexagon (hexagon.com) pioneers technology for assured positioning for land, sea and air. It powers intelligent positioning ecosystems in industries and safety-of-life applications, enabling the advancement of autonomous cars, UAVs, industrial vehicles, trains, vessels and more.
