# Resilient PNT and C-band navigation technology development > Live situation record from CLSTR: https://clstr.news/situations/resilient-pnt-and-c-band-navigation-technology-development > Updated: 2026-09-02T15:00:00.000Z. Sources: 4. Developments: 2. Developments in resilient Positioning, Navigation, and Timing (PNT) technologies have progressed through successful signal demonstrations and expanded testing capabilities. TrustPoint, in collaboration with Hexagon’s subsidiary NovAtel, demonstrated that C-band navigation signals can maintain precise positioning even when Global Navigation Satellite System (GNSS) signals, such as GPS, are subject to jamming or interference. This U.S. Navy-funded effort utilizes low Earth orbit satellites to provide navigation data independent of conventional L-band services. The demonstration utilized an enhanced NovAtel receiver to track these signals on an established commercial platform, intended to complement existing GPS for military and autonomous use in contested electromagnetic environments. In tandem with these signal advancements, Keysight Technologies has announced plans to showcase expanded PNT test and emulation capabilities. Following its acquisition of Spirent, the company aims to demonstrate sensor fusion—combining GNSS with inertial sensors and LEO PNT—to validate system performance against jamming and spoofing through multi-domain RF test environments. ## Timeline ### 2026-09-02: Navigation technology advances with C-band PNT and enhanced testing New advancements in resilient navigation include TrustPoint and NovAtel demonstrating C-band PNT signals during GNSS interference, and Keysight Technologies expanding its PNT testing and emulation capabilities. 2 sources. https://clstr.news/cluster/navigation-technology-advances-with-c-band-pnt-and-enhanced-testing ### 2026-08-26: TrustPoint demonstrates C-band signals capable of overcoming GPS jamming TrustPoint and NovAtel successfully tested C-band navigation signals that maintain precise positioning during GPS jamming, providing a resilient alternative for military and autonomous systems. 2 sources. https://clstr.news/cluster/trustpoint-demonstrates-c-band-signals-capable-of-overcoming-gps-jamming --- Cite as: Resilient PNT and C-band navigation technology development.
