Integrated guidance, navigation, and control system for a UAV in a GPS denied environment

초록

This paper proposes an integrated guidance, navigation, and control system for operations of a UAV in GPS denied environments. The proposed system uses a sensor combination, which consists of an image sensor and a range sensor. The main idea of the system developed is that it replaces the conventional navigation information with the measurement from the image processing. For example, it is possible to substitute the look angle and look angle rate from the image sensor for the conventional navigation information like the relative target position and the body angular rate. As the preliminary study, the integrated guidance and control system is designed with a nonlinear back-stepping approach to investigate the possibility of the proposed system. And the proposed integrated guidance and control system is verified by the numerical simulation. Copyright © 2018 by SCITEPRESS – Science and Technology Publications, Lda. All rights reserved
