Introduction
AND-FINS-98 FOG inertial navigation system (Substitute of PHINS) uses a three-axis fiber optic gyroscope to sense angular movement and output a digital signal proportional to the angular rate of carrier movement. The three quadrature collocations of the quartz accelerometer are used to sense the linear acceleration of the carrier and output a proportional current signal, which is converted into a frequency signal by the I-F conversion circuit, and finally input to the navigation computer. The computer completes the data reception of the gyroscope, accelerometer and external GPS, system compensation error calculation, navigation solution, and sends loop additional real-time speed, position, attitude and navigation information to the outside through the monitoring port.
The initial alignment of AND-FINS-98 is divided into two modes: static alignment and double position alignment. The position accuracy of the two position alignment is higher than that of the static alignment.
AND-FINS-98 has high precision and best stability and showed excellent performance in comparison test with PHINS related INS products.
