L3Harris has it available for U.S. armed forces across all programs and platforms.
We are proud to announce that L3Harris is the first company to achieve full approval for its M-code GPS receiver products. L3Harris M-code products are security certified, production qualified, and available to purchase for integration and operational use on DoD platforms.
Fixposition announced its new Vision-RTK positioning sensor, a compact centimeter-accurate solution with high reliability and availability in GNSS-challenged environments, at the Intergeo Digital event and industrial exposition. The sensor’s fusion algorithm deeply integrates satellite, camera and inertial sensors for reliability and availability in diverse and challenging applications.

Laboratory tests explore how commercially available receivers respond to meaconing and spoofing, with the goal of developing useful test methodologies and metrics to assess receiver robustness and resilience to real-world spoofing threats.
A new GNSS receiver for mobile consumer products uses only the modernized, wideband signals at L5, with an acquisition engine to acquire the signals directly and a navigation engine employing artificial intelligence techniques to fully exploit all the signals in L5’s 50MHz-wide band.
