The mathematical model evaluation error determine the extension time of the combat vehicle from the zone of «shade» in the line of sight of the goal

Abstract

In the considered assessment of the timing error for the nomination battle machines (firepower units) from the zone of «shading» in the zone of direct visibility goal. The dependence of this bias from the accuracy of the geographic information system of coordinates of the nearest chain border zone «shading», positioning accuracy vehicle navigation system and speed the movement of machine on the battlefield. The mathematical model of evaluation of error determine the time of the nomination battle machines from the zone «shading» in the zone of direct visibility goal. Mathematical modelling was conducted using the application package in Wednesday for the most common Maple arrangements combat vehicle to the nearest chain border zone «shading». It is shown that positioning error nearest to battle machine chain border zone «shading» geoinformation system and positioning errors of combat vehicle navigation system commensurate with the contribution to the total amount of error in determining the time of the nomination battle machines from the zone «shading» in the zone of direct visibility goal. The magnitude of the error in determining the extension time of the combat vehicle from the zone of «shade» in the line of sight of the goal decreases with increase in the speed of movement of the combat vehicle, and is increased by increasing the error of determining the coordinates of the nearest combat car circuit border zone «shading» and the error of determination of coordinates of a combat vehicle. The obtained analytical relation that allows to make demands to the magnitude of the measurement errors of the coordinates closest to the military machine of the circuit of the border zone, «shading» geoinformational system and coordinates combat vehicle navigation system according to the specified requirements for the size of the error in determining the extension time of the combat vehicle from the zone of «shade» in the line of sight of the target.
