CMC Electronics and Hexagon's autonomy and positioning division are developing technology that will mitigate global navigation satellite system (GNSS) jamming and spoofing using a multi-constellation, multi-frequency GNSS platform. Multi-constellation systems can receive position, navigation, and timing signals from more than one satellite navigation network, such as the U.S. GPS, Europe’s Galileo, Russia’s Glonass, and others.
Working with the autonomy and positioning division of Hexagon, CMC has made its “next-generation receiver,” which is certified to DO-254 level-A standards and incorporates Hexagon’s technology. The receiver also integrates inertial measurement unit inputs, as well as controlled reception pattern antennas. These antenna arrays can detect the difference in the direction between legitimate GNSS signals and jamming signals. Spacial filtering allows the receiver to remove the unwanted signals.
