In the initial alignment, the accuracy of static base alignment is mainly limited by the short
alignment time, the poor observability of azimuth misalignment, and sensor error. Traditional …

The large misalignment errors of horizontal and azimuthal angle cannot be converged
rapidly on the sea surface due to extra disturbance of linear and angular motions caused by …

This article investigates a novel Bluetooth odometer (BOD)-aided smartphone-based
vehicular navigation system for satellite-denied environments. First, a wheel-mounted BOD …

The integrated system with the strapdown inertial navigation system (SINS) and the global
positioning system (GPS) is the most popular navigation mode. It has been used in many …

The micro-electro-mechanical system (MEMS), with its small size, low cost and low power,
has attracted widespread attentions in recent year, and the initial alignment of the inertial …

To improve the alignment accuracy and environmental applicability of the micro-
