FIELD: physics. ^ SUBSTANCE: radio signals of navigation satellites (NS) are received successively through an antenna module, a radio signal distributor and a group of receivers. Each receiver performs amplification of NS radio signals, selection of the useful component from a mixture with interference and noise, conversion of the cleaned high-frequency radio signal into an intermediate using a radio-frequency module. Further, radio signals undergo functional transformation by providing support for basic modes for generating parameters and characteristics of an integrated navigation environment during aircraft landing. ^ EFFECT: broader functionalities. ^ 4 cl |
