High performance fiber optic inertial measurement unit-CFA130IC
Product Description
The CFA-130IC 3-axes FOG(fiber optic gyro) attitude and heading reference system has been designed to provide a cost effective, accurate geo-reference in harsh conditions without the need for an external GPS signal. The small size/volume makes it ideal for manual positioning in difficult physical locations.
Operation is based on inertial principles of initial gravity levelling using built-in accelerometers followed by geodetic heading calculation using the 3-axes gyroscopes, This alignment process requires 5 to 12 minutes dependent on latitude.
After inertial alignment the CFA-130lC gives continuous outputs of Heading. Roll and Pitch to enable subsequent movement of the target equipment to the required physical position.
Data read-out is achieved using a standard WiFi enabled device (such as smartphone, laptop) or using a custom PDA. in any case the JSON interface protocol can be hardware platform independent (eg i0S, Android, Win10) to suit the final application. A serial RS422 interface is also available.
Rugged environmental conditions were an important feature in the design of this unit internally with the high integration of electronics and sensors modelled using 3D CAD. This played a key role in keeping the unit shock & vibration resistant.
