Engineering and Operational Aspects of Miniature Marine Integrated Navigation and Stabilization System on Fiber-Optic Gyroscopes “KAMA-NS-V”

Abstract

Design features, operational aspects and main functions of the Miniature Marine Integrated Navigation and Stabilization System (MMINSS) “Kama-NS-V” based on a strapdown sensor unit of fiber-optic gyroscopes are viewed in this paper. Main operational modes are described. Grounds are given for the field testing procedure. Its advantage lies in the possibility of autonomous check of all input parameters in arbitrary motion. The results of trials in observational and autonomous modes including start-ups at latitudes higher than 70°N in rough sea and arbitrary motion conditions are presented. Comparative analysis of navigational and dynamic parameters accuracy relative to the gimballed INS currently used in the navy is provided.
