Centimeter-Level Accuracy

The highest precision positioning category with measurements within ±5-30 cm of true location. Achieved primarily using UWB technology with time-of-flight measurements. Essential for precision applications including AGV docking, robotic operations, and automated warehouse systems.

Positioning performance achieving errors under 10 cm, typically requiring Ultra-Wideband (UWB) technology. In industrial RTLS, centimeter-level accuracy enables applications requiring precise positioning: robotic guidance and AGV navigation, assembly process tracking where parts must be within tolerances, tool positioning in manufacturing cells, and high-density storage systems with narrow aisles. UWB systems achieving 5-15 cm accuracy (90th percentile) typically require: high anchor density (1 per 400-600 m²), good line-of-sight conditions, proper time synchronization (sub-nanosecond), high update rates (5-10 Hz), and careful calibration. Real-world centimeter accuracy is challenging to maintain consistently - metal surfaces create multipath, moving equipment causes temporary occlusions, and temperature variations affect signal propagation.

Applications genuinely requiring centimeter accuracy are relatively rare in industrial settings; many use cases (forklift tracking, personnel safety) perform adequately with 30-50 cm accuracy at significantly lower cost. When specifying centimeter-level accuracy, always clarify whether stated accuracy is 50th, 90th, or 95th percentile and whether static or dynamic conditions.
