Product Description

ORIENTUS
Orientus is a ruggedized miniature orientation sensor and AHRS that provides accurate orientation under the most demanding conditions. It combines temperature calibrated accelerometers, gyroscopes and magnetometers in a sophisticated fusion algorithm to deliver accurate and reliable orientation.

CALIBRATED DYNAMIC RANGING SENSORS

Orientus contains very high performance MEMs inertial sensors. These are put through Advanced Navigation's intensive calibration process to increase their performance further still and provide consistently accurate data over an extended temperature range of -40°C to 85°C. Advanced Navigation's custom calibration process is the only full sensor calibration that can provide dynamic ranging, allowing the user to select a sensor range for high accuracy or high accelerations on the fly. As part of this calibration, every Orientus unit spends 8 hours in our specially built rotating temperature chamber.

MAGNETIC INTERFERENCE MITIGATION

 

Orientus's advanced filter is able to detect when there is magnetic interference present and ignore magnetic data until the interference disappears. This allows Orientus to maintain accurate heading through periods of magnetic interference.

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 linear 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 and makes Orientus virtually immune to vibration.

MINIATURE RUGGED ENCLOSURE

 

Orientus's precision marine grade aluminium enclosure is waterproof and dirtproof to the IP68 standard and shockproof to 2000g, allowing it to be used in the most extreme conditions. It's minimal size, weight and power requirements allow for easy integration into almost any system.

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 protected from reverse polarity, overvoltage, surges, static and short circuits on all external interfaces.

Application

ROBOTICS

 

Orientus's accurate orientation data allows for stabilization of robotic systems. It's very high update rate allows it to control dynamically unstable platforms and it's focus on safety and reliability provides for piece of mind.

CAMERA STABILIZATION

 

Orientus can be used to stabilize camera gimbals allowing for smooth video from moving vehicles. It is also useful for targetting control on gimballed systems.

HUMAN MOVEMENT

 

Athletes and sports scientists can use Orientus to analyse human movement. Multiple units can be used to analyse kinematic joint movement. The extremely small size and weight allows the unit to be worn without impacting movement or performance.

MARINE

 

Orientus is excellent heading reference source for marine applications where its inertially fused magnetic heading is significantly more accurate than standalone magnetic heading sensors. It outputs true heading by default and is also able to provide magnetic heading.
