Polar Transversal Initial Alignment Algorithm for UUV with a Large Misalignment Angle [PDF]

open access: yesSensors, 2018
The conventional initial alignment algorithms are invalid in the polar region. This is caused by the rapid convergence of the Earth meridians in the high-latitude areas. However, the initial alignment algorithms are important for the accurate navigation of Unmanned Underwater Vehicles.

The misalignment angle in vessel-mounted ADCP

open access: yesOceanologia, 2000
A description of the misalignment angle and the consequences if it occurs is given. It is shown that because of gyrocompass errors, the misalignment angle error a has to be computed for each cruise.

A Calibration Method for Misalignment Angle of Vehicle-mounted IMU

open access: yesProcedia, Social and Behavioral Sciences, 2013
AbstractIn order to get accurate navigation data via Strapdown Inertial Navigation System (SINS), calibration of misalignment angle between Inertial Measurement Unit (IMU) and vehicle is necessary. The misalignment angle model is simplified, assuming that vehicle travels on a horizontal plane.
