Yost Labs introduces new high performance, low cost, ultra-miniature AHRS

New LX model provides Aerospace grade performance at consumer grade pricing.

PORTSMOUTH, Ohio—Yost Labs again raises the bar for advanced inertial motion tracking with their newest innovation, the 3-Space Sensor™ LX, an ultra-miniature Attitude & Heading Reference System (AHRS) with embedded pedestrian tracking and altitude estimation.

It is the smallest, fastest, most affordable sensor Yost Labs has ever produced. The high-precision, high-reliability, low-cost, AHRS uses triaxial gyroscope, accelerometer, and compass sensors along with a barometric pressure sensor in conjunction with advanced on-board filtering and processing algorithms to determine orientation relative to an absolute reference orientation in real-time. The combination of performance, size, and price of the 3-Space Sensor™ LX is unmatched by any competitors.

The new LX can reach sensor orientation outputs at up to 1750 Hz while automatically reducing the effects of sensor noise and sensor error. This ultra-fast filter update rate is due to the sophisticated engineering of Yost Labs’ proprietary sensor fusion algorithm, QGRAD2™ which is over 10 times more efficient than existing Kalman filter algorithms.

Measuring 6x15x1.7 mm, the reengineered 3-Space Sensor™ is 5.8 times smaller than the previous model and weighs only 0.9 grams. Drawing just 22mA @ 5v, it is also over twice as energy efficient as the original embedded sensor.

This model also features advanced on-board magnetometer auto-calibration which allows the sensor to quickly adapt to changing magnetic environments. This breakthrough in automation increases ease of use with faster set up and more accurate results.

An additional highlight of the sensors will be support for pedestrian tracking by computing and storing an estimated motion path of a walking individual carrying or wearing the sensor. With this, the Yost Labs team has solved the significant challenge of tracking where a person is as they walk around and even climb stairs in a building or other environment where GPS is not available.

Other application areas for the 3-Space Sensor™ LX include robotics, motion capture, unmanned navigation, healthcare monitoring, virtual reality and immersive simulation, and more.

With the 3-Space Sensor™ LX, Aerospace grade AHRS is now available at consumer grade pricing. Development kits will be available for only $99 and 3-Space Sensor™ LX will start at $75 each with volume discounts available. Additional pricing information is available by contacting Yost Labs.
