Yost Labs designs and manufactures 3-Space™ AHRS/IMU/VRU sensors in Ohio. Our sensors combine triaxial gyroscopes, accelerometers, and magnetometers with proprietary QGRAD3 sensor fusion to deliver accurate orientation and position in real time. Defense teams use them for GPS-denied navigation. Robotics and automation engineers use them for stabilization and control. Medical and sports researchers use them to measure human motion.
The 3-Space™ Sensor Family, v3
Every 3-Space™ sensor shares the same core: a 10 DOF inertial platform, QGRAD3 sensor fusion at up to 2000Hz, and the World Magnetic Model (WMM) for true heading anywhere on Earth. Choose the form factor that fits your design.

Why engineers choose 3-Space™ Sensors
GPS-denied navigation. EEPTS pedestrian tracking, developed under defense-funded programs, delivers position within 3% of distance traveled with no satellite signal.
QGRAD3 sensor fusion. Our patented filter outperforms Extended Kalman Filter approaches with lower latency and a fraction of the computational load.
Proven in the field. Specified by defense primes, allied militaries, robotics leaders, and medical device developers.
