Ballistic Yaw Sensor
Accuracy. Speed. Compliance.
The Biokinetics® Ballistic Yaw Sensor (BYS) is a precision imaging system designed to measure projectile yaw angles with traceable accuracy. With fast and easy set-up, the system delivers rapid, repeatable results. The Ballistic Yaw Sensor is a modern alternative to legacy yaw card methods that is 40% faster and far more efficient.
Key Benefits
- High-Speed Accuracy
Angular accuracy of ±0.5° for yaw measurements of bullets and fragments. - Image-Based System
High-speed CMOS camera and LED lighting enable high-resolution yaw detection just 10 cm from target. - Standards-Aligned
Complies with NATO, NIJ, and international armor test standards requiring yaw ≤ 3° (rifle) or ≤ 5° (handgun/FSP). - Fully Integrated Workflow
Automated image capture, yaw calculation, data storage, and traceable system calibration. - Repeatable Positioning
Can be positioned up to 10 cm from the impact zone, minimizing distance error and allowing near-target measurement.

Advanced Yaw Measurement Technology
Projectiles exiting a firearm often travel with a non-zero angle of attack, creating a misalignment between their axis of symmetry and line of flight. This yaw angle plays a critical role in aerodynamics and penetrative behavior, especially for armor-piercing threats. The Biokinetics Yaw Measurement System captures high-speed imagery of bullets and fragment simulating projectiles, enabling accurate yaw quantification at close range.
High-Performance Imaging System
Equipped with a 5-megapixel monochrome CMOS camera and high-intensity COB LED light source, the BYS captures sharp images with exposure times under 500 ns. Measurement data is processed via purpose-built software, delivering selectable speed inputs and precise yaw readings across a wide range of projectile types.
Optional Accessories
- Adjustable floor stand with 4-axis positioning for repeatable alignment
- Integrated gauge – simplifies setup using an in-bore laser
- Spall protector plate and bracket system
- Extended cabling and accessory kits
