ICE AND ENVIRONMENT MONITORING SYSTEM Russian patent published in 2020 - IPC G01C21/00 G01W1/02 

FIELD: navigation; automated monitoring.

SUBSTANCE: invention relates to automated monitoring of state of ice and environment with simultaneous determination of coordinates of own location of complex and transmission of obtained information via radio channel. Measuring and navigation system comprises housing 1, GPS signal receiver 3, control unit 2.1, atmosphere condition determination unit 4, ice cover thickness determining unit 5, accumulator battery state determining unit 6, power supply unit 7 and transceiver unit made in form of first radio stations 8.1. Stationary monitoring station (SMS) is made in form of second radio station 8.2. Each radio station 8.1 (8.2) comprises control unit 2.1 (2.2), synchronizer 16.1 (16.2), PCP generator 17.1 (17.2), carrier frequency synthesizer 18.1 (18.2), phase manipulator 19.1 (19.2), synthesizer 20.1 (20.2) of frequencies of the first heterodyne, first mixer 21.1 (21.2), first intermediate frequency amplifier 22.1 (22.2), first power amplifier 23.1 (23.2), duplexer 24.1 (24.2), transceiving antenna 25.1 (25.2), second power amplifier 26.1 (26.2), second heterodyne frequency synthesizer 27.1 (27.2), second mixer 28.1 (28.2), amplifier 29.1 (29.2), second intermediate frequency, multiplier 30.1 (30.2), band-pass filter 31.1 (31.2), phase detector 32.1 (32.2). GPS signal receiver 3 comprises receiving antenna 9, power amplifier 10, mixer 11, a second intermediate frequency amplifier 12, multiplier 13, band-pass filter 14 and phase detector 15. Ice and environment monitoring system comprises measurement and navigation system (SNC) installed on drifting ice, stationary monitoring station (SMS), GPS-satellites and AES transponder S.

EFFECT: technical result is improved reliability of radio telemetry and command information exchange between measurement and navigation system.
