This transmitter will transfer differential corrections to aircraft navigational sestems from reference stations. Taking into account the high requirements of resistant to interference it is necessary to use 8-level relative phase manipulation and cyclical codes for increasing of data tfansfer speed. The version of the transmitter functional construction on the basis of modulator direct digital synthesis, using of spesial processors and integral schemes with programmed logic is developed. The mathematical models are developed, which allow to estimate sensitivity of the modulator to the main destadilizing factors. Product Description popup.authors popup.nrat_date 2020-04-02 Close
