High performance fiber optic inertial measurement unit-CFA300X
Product Description
The CFA-300X is a slim (OD 1.6") 3-axis FOG attitude and heading reference system designed specifically for horizontal drilling applications (HDD), Internal design comprises an advanced solid-state 3-axis fiber-optic (FOG) inertial measurement unit with highly integrated digital electronics and CPU, The proven MWD crossovers are designed to be mounted in the bottom hole assembly (BHA) of a drill collar. An advanced AHRS algorithm with Kalman Filter continuously monitors sensor performance to provide optimum accuracy in all conditions.
After initial alignment, the CFA-300X enters navigation mode andprovides continuous updates of heading, roll and pitch when reguested via the client-server RS485 interface. lf necessary, gyrocompassing can be perormed at anytime when stationary.
