Evaluation of the influence of the relative position of the navigation system on the accuracy of determining the location of an unmanned aerial vehicle

The sequence of formation of formulas of the geometric factor, the influence of which determines the geometry of the working constellation of navigation spacecraft in solving problems of determining the location of an unmanned aerial vehicle, is carried out. The need to solve the problem of increasing the accuracy of navigation inevitably leads to an increase in the GLONASS orbital constellation. It is shown that the geometric factor has a significant effect on the standard deviation of the navigation error, and with an increase in its value, the error increases. A method for determining the best value of the geometric factor is presented. The proposed method can be used in the control complex of an unmanned aerial vehicle.
