METHOD Ice receiving signals of satellite navigation systems in finding underwater objects NAVIGATION ON THE HORIZON WITH CHANNEL hydroacoustic shipping information

摘要

Method ice reception of signals of satellite navigational systems when the underwater object on the horizon navigation using sonar transmission channel navigation information comprising administered in an ice receiver antenna satellite navigation system in place priledneniya this antenna to the lower edge of the ice, the reception of the antenna spacecraft signal receiver measurement the parameters of these signals and on data obtained by determining the required computing corrections to the geodetic schislimym CCW ordinates and rate generated by an onboard inertial navigation system of the underwater object implementation by considering these amendments correction onboard inertial navigation system, which is supplied from the horizon swimming underwater object to place priledneniya to the lower edge of the ice antenna with the receiver signal of the satellite navigation system and with its introduction mechanism ice, dual responder beacon, which has a different request codes and different frequencies emitted by the sonar signal rates, the caliper and sound propagation in water and hydrostatic sensor, implementing an antenna with the receiver signal of the satellite navigation system in the ice at the place of its priledneniya to the lower edge of the ice through the introduction of a mechanism to the exit side of the antenna of ice into the air, and underwater objects using a dual-channel sonar system two sonar priemoizluchayuschimi antennas, one priemoizluchayuschuyu sonar antenna is installed at a predetermined location in the feed, and other sonar and priemoizluchayuschuyu
