摘要

This paper treats the problems of strapdown navigation calculation in the context of vibration-induced error and designing sculling-algorithms, which are tailored to the IMU-sensor dynamic characteristics. An appropriate integration algorithms structure and optimization procedure accounting for IMU data frequency shaping are derived. It is proposed a new formulation of the error minimization criterion, which provides error-free algorithm response to vibrational motion at some fixed frequency. Also addressed here are the problem of pseudo-sculling error minimization and approach to tailoring sculling algorithms to the frequency responses of the feedback type sensors.
