Orientus Miniature AHRS

Compact, rugged AHRS for stabilization and control

Orientus Miniature MEMS AHRS for stabilization and controlOrientus is a ruggedized miniature orientation sensor and AHRS (Attitude & Heading Reference System) that combines temperature calibrated MEMS accelerometers, gyroscopes and magnetometers using a state-of-the-art fusion algorithm to deliver accurate and reliable orientation in even the most demanding environments.

Orientus features advanced filtering that detects and adjusts for magnetic interference. Its sophisticated algorithm compensates for short-term linear accelerations, allowing the sensor to maintain accurate roll and pitch measurement. Long term linear accelerations can also be dealt with via addition of an external GNSS receiver for full linear acceleration compensation.

Orientus Rugged AHRS for UAV stabilizationOrientus is enclosed in a precision-machined marine grade aluminium enclosure. Waterproof and dirtproof to IP68 standard and shockproof to 2000g, the system maintains high reliability in the most extreme conditions. The minimal size, weight and power requirements make it ideal for unmanned vehicle applications such as platform and camera stabilization, as well as a heading reference source for unmanned surface vehicles.

Motus Miniature MEMS IMU

Ultra-high accuracy miniature inertial sensor for UAVs

Motus Miniature MEMS IMU for UAVMotus is a miniature ultra-high accuracy MEMS IMU (inertial measurement unit) that combines ultra-high accuracy accelerometers and gyroscopes with magnetometers to provide inertial performance that exceeds even some FOG IMUs.

With a volume of just over 1 cubic inch and a weight of only 26 grams, Motus is ideal for SWaP-conscious applications, such as geopointing and LiDAR missions with VTOL UAVs. The system is available in an OEM package suitable for integration into larger products, or an enclosed package for external and standalone use.MOTUS+ OEM MEMS IMU

Motus can be upgraded to full AHRS or INS capability through a simple software license upgrade. With INS capability it can be interfaced to many leading brands of GNSS receivers to create a complete OEM GNSS/INS solution.

  • 0.1 ° Heading
  • 0.2 °/hr Gyro Bias Instability
  • 1000 Hz Update Rate
  • 2000 g Shock Limit

Key Features:

  • Hot Start Time : 2 seconds
  • IMU, AHRS and INS options
  • 2 versions : OEM or Rugged


Certus and Certus Evo GPS-Aided INS & AHRS

Rugged low-SWAP positioning solutions for UAVs and Robotics

Certus and Certus Evo are rugged low-SWaP, ITAR-free GPS-aided INS and AHRS modules that combine temperature-calibrated accelerometers, gyroscopes, magnetometers and a pressure sensor with a dual antenna RTK GNSS receiver, all coupled with a cutting-edge AI-based sensor fusion algorithm.

Certus modules incorporate dual antenna moving baseline RTK, providing highly accurate heading data for both stationary and moving vehicles even in magnetically problematic environments.

The RTK GNSS receiver provides up to 8mm accuracy positioning and supports all of the current and future satellite navigation systems.

Certus and Certus Evo are ideal for UAV and USV surveying, antenna and weapons platforms targeting, and stabilization of robotic systems.
