Description
This product attitude north finder is a full-attitude north finder, which can be installed on the carrier as an independent operating unit. The system adopts a high-precision three-axis fiber optic gyro and three-axis accelerometer to independently calculate the attitude Angle including heading Angle through the inertial device sensitive to constant physical quantities such as earth rotation and gravity acceleration, so as to realize the functions of high-precision autonomous north finding and attitude measurement under horizontal or non-horizontal conditions. At the same time, the attitude Angle measured by the instrument and its incremental data can be output at high frequency continuously, which is convenient for the carrier’s control system to realize various real-time applications such as azimuth correction and dynamic servo.
This product attitude north finder has the advantages of high precision, long life, significant resistance and electromagnetic field interference resistance.
