The Sensor Stack
Modern navigation relies on Sensor Fusion. No single technology is perfect. We analyze the four pillars of modern PNT based on five key metrics: Accuracy, Cost Efficiency, Autonomy (Jamming Resistance), Scalability, and Maturity.
⎈ Advanced GNSS
Multi-frequency satellite systems with Real-Time Kinematics (RTK) for cm-level accuracy.
⟐ Inertial (INS)
Self-contained gyroscopes and accelerometers. Completely un-jammable but suffers from drift.
👁 Visual SLAM
Simultaneous Localization and Mapping using cameras/lasers. Ideal for GPS-denied local areas.
⚛ Quantum
Cold-atom interferometry offering near-perfect accuracy without drift. Currently expensive and bulky.
The Strategic Landscape
Comparing the trade-offs between System Cost, Accuracy, and Technical Maturity.
* Bubble Size = Technical Maturity (Larger is more mature)
GNSS & Mechanical INS are industry standards.
Visual SLAM is dominating robotics.
Quantum sensors are the future frontier.
