Unmanned aerial vehicle position determination in GNSS landing system

Due to significant potential benefits provided by unmanned aerial vehicles, their usage continues to grow in different application spheres. Development of reliable unmanned aerial vehicle navigation and control systems, and landing system, in particular, conclude very complex and interesting task, with which engineers and designers face. This paper presents the method of unmanned aerial vehicle position determination in Global Navigation Satellite System landing system for the cases when precise coordinates of reference receiver and runway are unknown and when they are known in advance. It has been experimentally proved the correctness of the presented method for the case when unmanned aerial vehicle is landing at the airdrome with precisely defined Final Approach Segment data block parameters.
