INFLUENCE OF ERRORS OF TOPOGRAPHIC SURVEY AND ORIENTATION OF RADIO- TECHNICAL MEANS OF AIRSPACE CONTROL ON ESTIMATES OF COORDINATE INFORMATION ISSUED BY THEM

Abstract

The last decade is characterized by a number of military conflicts, in most episodes of which the achievement of the goal (reconnaissance and (or) defeat of certain targets) by the warring parties is mostly achieved through the use of aircraft, including small and (or) unmanned. The main difference is to obtain the desired results without a direct collision with the enemy ground component of troops (forces).
 Most of the recommended measures to combat aircraft in modern conditions can be reduced to: the rational construction of battle order (using the air defense separation), the widespread use of covert communications, radio reconnaissance and electronic warfare, the creation of erroneous and camouflage combat (reserve) positions of air defense means , automation of transmission and processing of information about the air situation with the use of modern technologies and increase the accuracy of coordinate information provided to combat (or fire) means.
 Improving the accuracy of coordinate information causes: the possibility of searchless detection and (or) capture of air targets by fire, increasing the survivability of air defense systems by reducing working hours (including time for "radiation") and rapid change of their positions after the task. Modern algorithms for processing coordinate information provided by air defense systems take into account the errors of measurement of primary coordinates by radio engineering, the delay time of information in communication channels and its possible distortion. At the same time, they do not explicitly take into account the influence of topographic errors and orientation errors of radio equipment.
 In the work, with the use of methods of mathematical statistics and mathematical modeling, the analysis of influence of topographic errors and orientation of radio-technical means of airspace control on estimations of the coordinate information issued by them is carried out. The obtained ratios allow to make an appropriate assessment and provide recommendations for further research.

 The obtained results can be used in tests of radio-technical means of information support, in information processing algorithms and automated control systems.
