Abstract


The key actions for the implementation of the global navigation satellite systems are described in this article. At the testing stage, the conformity of the system with the operating standards is established, its accuracy characteristics are proved, the temperature of the control bodies and the units are measured, in addition, the composition of the aircraft explores the electromagnetic compatibility of the navigation satellite systems with the equipment of the aircraft.Failure to recognize the deficiencies at the testing stage will lead to significant economic losses in the implementation and refinement of already certified fleet of aircrafts, and worsening of safety flights. Therefore, it is very important to consider all the factors that may affect the work of the system, such as: the temperature of the outside air, the position of the aircraft in space, the connection of the navigation satellite systems with the equipment of the aircraft with partial and complete failure of this equipment, etc. The main but not the only parameter of the navigation satellite systems is precision characteristics, which together with the precise characteristics of manual or automatic control of the aircraft, allow us to meet the requirements of the concept of zonal navigation, which greatly expands the technical capabilities of the aircraft. Therefore, the article pays special attention to the precision characteristics of the navigation satellite systems, methods for increasing the accuracy of statistical analysis of data by: 1) the method of maximum likelihood or nonlinear least squares; 2) the method of simultaneous determination of state variables and Kalman filtration parameters and nonlinear estimation.
