Problem of Realization on Integer CCS (as “Malachite-3”) the Algorithm of Gauging SINS in Flight Using Information from High-Precision INS

Abstract

The paper is devoted to the formulation of the problem for vector matching for strapdown inertial navigation system (SINS), allows to gauge gyro and accelerometer sensors of SINS, and to the problems of realization an vector matching algorithm on digital computing system (DCS), which operates with a fixed point number, an example of which is the DCS “Malachite-3”. The results of mathematical modeling for gauging 4 gyro sensors of SINS, based on a fiber optic gyroscope, via vector matching with the high-precision inertial navigation system, based on the gyroscopestabilized platform, are presented. The results of algorithm realization for vector matching on DCS “Malachite-3” with 32-bit arithmetic are presented. Also presented the estimated time required for computation of the algorithm.
