COMPUTER SYSTEM FOR REMOTE CONTROL OF NAVIGATION SYSTEMS FOR AUTOMATED MONITORING OF ENVIRONMENT IN ARCTIC CONDITIONS Russian patent published in 2020 - IPC G01C21/00 

FIELD: physics.

SUBSTANCE: disclosed system relates to the field of automated monitoring of the environment in Arctic conditions, specifically the state of the atmosphere and ice with simultaneous determination of the coordinates of the navigation systems own location and transmission of the received information over radio channels, and can be used as an environment monitoring device in the ice movement area for safe navigation of vessels along the northern sea route and provision of safety of oil-and-gas field objects and hydraulic engineering infrastructure on shelf and in coastal zone in Arctic seas and in conditions of ice cover, including drifting. Computer system for remote control of navigation systems for automated monitoring of the environment in Arctic conditions comprises a dispatcher station (DP), navigation systems (HKi, i = 1, 2, …, n) and satellite communication system (SC) space vehicles. Each transceiving device 1 (1.i) comprises control unit (2i), computer 3 (3.i), driving oscillator 4 (4.i), modulator code generator (5i) (5.i), phase manipulator 6 (6.i), first heterodyne 7 (7.i), first mixer 8 (8.i), amplifier 9 (9.i) first intermediate frequency, first power amplifier 10 (10.i), duplexer 11 (11.i), transceiving antenna 12 (12.i), second power amplifier 13 (13.i), second heterodyne 14 (14.i), second mixer 15 (15.i), amplifier 16 (16.i) a second intermediate frequency, multiplier 17 (17.i), band-pass filter 18 (18.i), phase detector 19 (19.i), receiving antenna 20.i, GPS signal receiver 21.i, ice thickness measurement unit 22.i, atmospheric state measurement unit 23.i, underwater navigation beacon 24.i, oscillatory circuit 25 (25.i), narrow-band filter 26 (26.i), amplitude detector 27 (27.i), threshold unit 28 (28.i) and switch 29 (29.i).

EFFECT: technical problem of the invention is high selectivity, noise immunity and reliability of duplex radio communication between the control centre and navigation systems by suppressing false signals (interference) received over additional channels.
