This paper revisits the stationary alignment problem of attitude and heading reference
systems (AHRSs). The investigation is initiated from the three-axis attitude determination …

This paper presents an enhanced algorithm for inertial gyrocompassing using strapdown
sensors, which performs faster than the other available ones. The proposed algorithm is …

This paper revisits the stationary attitude initialization problem, ie, the stationary alignment,
of Attitude and Heading Reference Systems (AHRSs). A detailed and comprehensive error …

As an important deterministic error of the inertial measurement unit (IMU), the installation
error has a serious impact on the navigation accuracy of the strapdown inertial navigation …

To solve the problem that the ship's strapdown inertial navigation system (SINS) alignment
accuracy decreases with the increase of the nonlinear filtering state dimension under …

In this note, the feasibility of initial alignment of a gyro-free inertial navigation system (GF-
INS) is investigated. Initial roll and initial pitch are obtained using leveling of conventional …

For the optimization and algorithm design of high precision strapdown inertial navigation
system (SINS), a systematic and fine attitude error analysis method is needed. To this end, a …

This paper derives an improved multistage in-motion attitude determination alignment
(IMADA) for strapdown inertial navigation system, which integrates the traditional IMADA …

In order to accurately calibrate the static error model coefficients of three gyroscopes
simultaneously, especially the higher-order coefficients, in an inertial measurement unit, an …
