It used a comprehensive approach to the development of all elements of the system, including the codec and modem, transmission line, as well as the definition of appropriate criteria for reliability and regulation of calibration work. The functional circuits of the synthesizer of the modified PSK signal with pi ±pi / 2 phase shifts, appropriate receiver structures for such signals, potential channel selectivity have been determined. The antenna feeder devices for the case of the terrestrial transmition line based on this type of signal have been developed, the system performance criteria and the calibration rules have been determined.
