Analysis of error for a rotating strap-down inertial navigation system with fibro gyro

Abstract

The error equation of a rotating inertial navigation system was introduced. The effect of the system’s main error source (constant drift of gyro and zero bias of accelerometer) under rotating conditions for the system was analyzed. Validity of theoretical analysis was shown via simulation, and that provides a theoretical foundation for a rotating strap-down inertial navigation system during actual experimentation and application.
