Urgent problems of UAV navigation system development and practical implementation

Unmanned aerial vehicles are successfully exploited in different spheres of humans' life for the last decades. At tremendous increase of UAV-related market it is very important to develop own reliable and accurate navigation and automatic flight control systems. This paper presents some questions related with navigation system development and practical implementation. Its prototype has been developed in Aerospace Center of National Aviation University. The results approving integrated navigation system efficiency of functioning from one of the experimental validations have been presented.
