Ve FINS-98 Yüksek Performans 

Giriiş
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.
Ve FINS-98'in ilk hizalaması iki moda ayrılır: statik hizalama ve çift konum hizalaması. İki konum hizalamasının konum doğruluğu, statik hizalamadan daha yüksektir.
Ve FINS-98, yüksek hassasiyet ve en iyi kararlılığa sahiptir ve phinlerle ilgili INS ürünleri ile karşılaştırma testinde mükemmel performans göstermiştir.
