GNSS-Denial Quantum Navigation

Описание: Modern Cold Atom Gravimetry: Hybrid Fusion and Field Operation
These documents provide a comprehensive technical framework for advancing cold atom gravimetry and GNSS-denied navigation systems, specifically for mobile platforms like UAVs and aircraft. They detail the transition from laboratory quantum sensors to miniaturized, field-ready hardware such as grating magneto-optical traps and titanium vacuum packages. A significant portion of the text focuses on sensor fusion, explaining how Extended Kalman Filters combine precise quantum data with high-rate classical accelerometers to correct for environmental noise and motion effects. The sources also offer practical engineering blueprints for dual-axis stabilized platforms and gimbals designed to maintain vertical alignment during transport. Furthermore, the material evaluates various positioning strategies—including visual odometry and terrain-referenced navigation—to ensure operational continuity when satellite signals are unavailable. Finally, the collection includes Python simulations and mathematical models to predict the performance and sensitivity of these hybrid sensing technologies in real-world scenarios.
As of 2025, cold-atom gravimetry and inertial sensing have transitioned from high-precision laboratory experiments to robust, field-deployable systems (TRL 5–6). The primary driver of this evolution is the necessity for resilient Positioning, Navigation, and Timing (PNT) in GNSS-denied environments. Modern architectures achieve tactical and strategic-grade performance by synthesizing three core pillars: hardware miniaturization (atom chips and integrated optics), hybrid sensor fusion (Kalman filtering of classical and quantum data), and novel trap geometries (ring-trapped Sagnac interferometers). These systems offer drift-free operation with absolute calibration, providing a decisive advantage for autonomous systems, submarines, and hypersonic vehicles.
