An integrated aircraft navigation system with optical horizon sensor
Abstract
An integration algorithm for a strapdown inertial navigation system with optical horizon sensor based on Kalman filtering is presented. It allows the accuracy of the estimation of aircraft motion parameters to be improved. A self-contained horizon recognition algorithm for the video sequence that enables real-time aircraft attitude determination relative to the horizon line is developed. A scaled-down simulation and performance analysis of the operation of the integrated navigation system is carried out.
