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.

Reliability

Orientus has been designed from the ground up for mission critical control applications where reliability is very important. It is built on top of a safety oriented real time operating system and all software is designed and tested to safety standards with fault tolerance in mind. The hardware is designed and manufactured to mil standards.
