Recovery of GPS Disability to Unmanned Aircrafts by System Modeling

Abstract

In the proposed development, a modeling of the operation of the NAVSTAR-GPS system, determining the positions of the satellites and the distances to them is made. The information obtained in this way is entered into the computer for control of an autonomous unmanned aerial vehicle, and the data of the satellites that have failed from the working constellation are replaced with those from the model. The main goal is to improve the accuracy and reliability in piloting and navigation of unmanned aerial vehicles.
