Acc.elerometer vs NAC

Transform your device into a powerful motion sensor laboratory. Record and visualize real-time data from your device's built-in sensors with interactive charts and precise measurements. Perfect for researchers, developers, students, and anyone interested in understanding device motion. Supported sensors: • Accelerometer – Total device acceleration including gravity (G-force) • User Acceleration – Pure motion acceleration without gravity influence • Gyroscope – Rotation rate around all three axes (rad/s) • Magnetometer – Magnetic field strength and compass data (μT) • Device Attitude – 3D orientation in space (roll, pitch, yaw) • Gravity – Isolated gravitational force vector (G-force) Key features: • Real-time sensor visualization with smooth, interactive charts • Manual start/stop control for targeted data collection • Export any recording as timestamped CSV files • Customizable recording sessions with precise timing control Export analysis: All sensor data exports as CSV files with timestamps, making it seamless to import into any data analysis platform. Start recording with a single tap and unlock the hidden motion story of your device.

This 3-axis mobile iOS™ application enables airport operators to "spot-check" contaminated surfaces during winter runway operations. Key Features: Accurate Measurements: Records vehicle braking values by measuring the "g" force or lock-wheel braking action during qualified tests. Automated Reporting: Automatically generates final reports segmented into runway thirds: "touchdown," "midfield," and "rollout." Comprehensive Data Recording: Captures all necessary data, including time, date, operator, and assigned user ID. Versatile Contaminant Selection: Allows operators to choose from 14 different contaminant types for reporting runway conditions during winter operations. Easy Data Export: Supports exporting results using the standard print function. Additional Information: The NAC-DFD® assists airport operators in assessing the effectiveness of friction-enhancing treatments by indicating trends in runway friction levels. It is approved by the Federal Aviation Administration, as listed in Advisory Circular 150/5200-30C, Appendix 3. Note: For continued testing, a subscription is required.
