3-Space™ Sensor Wireless

Miniature AHRS / IMU with Wireless Communication Interface

3-Space Sensor WirelessThe 3-Space Sensor Wireless integrates a miniature Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU) with a 2.4GHz DSSS wireless communication interface that delivers high performance at ranges of up to 200 feet. An integrated Lithium-Polymer battery and charge control gives a battery life of 5+ hours at full performance.

As with all our 3-Space sensors, orientation can be returned in absolute terms or relative to a designated reference orientation. The gradient descent calibration process and high update rates increase accuracy and greatly reduce and compensate for sensor error. The 3-Space Sensor system also utilizes a dynamic sensor confidence algorithm that ensures optimal accuracy and precision across a wide range of operating conditions.

3-Space™ Sensor Embedded

Ultra-Miniature Surface-Mount AHRS / IMU

3-Space Sensor EmbeddedThe 3-Space Embedded is an ultra-miniature Attitude and Heading Reference System (AHRS) / Inertial Measurement Unit (IMU) produced in a surface-mount assembly. Measuring 23mm x 23mm x 2mm and weighing only 1.3 grams, it is our smallest and lightest high-performance AHRS, making it ideal for space-constrained unmanned vehicle applications.

As with all our 3-Space sensors, the Embedded module features are accessible via a well-documented open communication protocol that allows access to all available sensor data and configuration parameters. Versatile commands allow access to raw sensor data, normalized sensor data, and filtered absolute and relative orientation outputs in multiple formats including: quaternion, Euler angles (pitch/roll/yaw), rotation matrix, axis angle, two vector (forward/up). The Embedded module also offers a range of communication interface options, including SPI, USB 2.0, and asynchronous serial.

Specifications:
