An Autonomous Vehicle Navigation System Based on Inertial and Visual Sensors
Sensors, 2018 The strapdown inertial navigation system (SINS) is widely used in autonomous vehicles. However, the random drift error of gyroscope leads to serious accumulated navigation errors during long continuous operation of SINS alone.

A New Analytic Alignment Method for a SINS [PDF]
, 2015 Analytic alignment is a type of self-alignment for a Strapdown inertial navigation system (SINS) that is based solely on two non-collinear vectors, which are the gravity and rotational velocity vectors of the Earth at a stationary base on the ground. The

IET Radar, Sonar &Navigation, Volume 15, Issue 4, Page 419-430, April 2021., 2021 Abstract This study investigates two fundamental challenges in the initial alignment of strapdown inertial navigation systems and presents creative solutions to overcome these challenges. The first challenge is to determine the settling time in different operating conditions such as stationary, quasistationary, in‐motion, etc.
