Methods of correction of navigation systems and navigation complexes

The article considers methods of correction of navigation systems (NS) and navigation complexes (NC) on the basis of information received by aircraft control devices (AIR). It is taken into account that the NC includes gyroscopic systems, various radar stations (radars), other navigation and orientation systems, as well as GPS or GLONASS. Errors of autonomous navigation systems, algorithmic methods of compensation of errors of navigation systems and complexes are considered. The inertial navigation system (INS), which is the basic system of the NC, is considered separately, and its errors are divided into methodical and instrumental. Cases are taken into account when it is impossible to correct the NC aircraft due to the temporary absence of a signal from an external source of information. Satellite emergency signals are subject to active and passive interference. The methods of using autonomous INS correction algorithms taking into account the algorithms of estimation, control, complexation and forecasting are investigated
