Miniature AHRS Orientus (NRND)

Orientus is a miniature IMU and AHRS that provides accurate orientation under the most demanding conditions. Roll & Pitch 0.2 ° Heading (Magnetic) 0.8 ° Bias Instability 3 °/hr Update Rate 1000 Hz Orientus combines temperature-calibrated accelerometers, gyroscopes, and magnetometers with a sophisticated fusion algorithm to deliver accurate and reliable orientation. It is available in both OEM and rugged packages. Features High-Performance MEMS Orientus contains high-performance MEMS sensors that are put through Advanced Navigation’s intensive 8-hour temperature calibration process. This provides the highest accuracy possible from this sensor class and outputs consistent accuracy over the full temperature range from -40°C to 85°C. Automatic Magnetic Calibration Orientus features fully automatic magnetic calibration that updates every time the unit moves and removes all requirements on a manual calibration process. This provides reliable accurate heading through changing environments. Linear Acceleration Compensation Orientus uses an innovative algorithm to compensate for linear accelerations. This allows Orientus to maintain accurate roll and pitch through short term linear accelerations that typically cause significant errors in competitors systems. For long term linear accelerations Orientus supports the addition of an external GNSS receiver for full acceleration compensation. High Update Rate Orientus’s internal filter runs at 1000Hz and data can also be output at this rate over high speed RS232. This allows for control of dynamically unstable platforms.
