Development of a model for calculating the dilution of precision coefficients of the global navigation system at a given point in space

In this article, a model for calculating the coefficients of dilution of precision of object positioning using the Global Navigation Satellite System is proposed. The proposed model makes it possible to obtain the values of the coefficients of position dilution of precision of a manned aerial object for a certain period of time in a given area. The dependence of the growth of the dilution of precision coefficient on the number of satellites over a given area is established. It is shown that, when the number of satellites over a given area is 4 or less, the value of the coefficient of the position dilution of precision reaches a value of more than 20 units. The model presented for assessing the accuracy of the Global Navigation Satellite System can be used to evaluate the effectiveness of the use of manned aerial objects when they perform humanitarian, evacuation, rescue and logistics activities in a given area.

Keywords:
