RECEIVER IN EQUIPMENT OF USERS OF SIGNALS OF GLOBAL SATELLITE RADIO NAVIGATION SYSTEMS Russian patent published in 2002 - IPC

FIELD: satellite radio navigation. SUBSTANCE: invention can find use in paths of primary processing of information signals of global navigation systems GPS NAVSTAR (USA) and GLONASS (Russia). Receiver in equipment of users of signals of global radio navigation systems has two antennas, two band-pass filters-preselectors, three low-noise amplifiers, superhigh-frequency switch, reference thermostated generator, two formers of spectrum of reference frequencies, five mixers, five band-pass filters, three intermediate frequency amplifiers, two automatic gain control units, two low-pass filters, two analog-to-digital converters, calibrator and fourth intermediate frequency amplifier. Achievable technical result of invention consists in possibility of calibration of receiving-amplifying path of said receiver, in automated control over operation of navigation satellites of systems NAVSTAR and GLONASS, in test of serviceability of receiver in equipment of users of signals of global satellite radio navigation systems, in increased reliability of employment of signals of global satellite navigation systems mounted on civil aviation aircraft and helicopters, in reduced irregularity and strict recording of group delay time in channel of reception and processing of character frequencies of radio navigation system GLONASS. EFFECT: enhanced functional reliability and efficiency of receiver. 5 dwg
