“…5c 3. Elements of the structure of the above water part of the radio buoy: (1) housing, (2,14) end lids with circular sealing gas kets, (3,6,9,16) circular gaskets, (4) radio antenna, (5) stud, (7) washer, (8) nut, (10) sealed electrical connector, (11) switch, (12) plug with a gasket, (13) clamp washer with a gasket, (15) eye bolt, (17) in the temperature at the point of the buoy location. The temperature sensor clearly detected the arrival of a train of transformed internal waves at the coastal zone during high tide and a decrease in the tempera ture in the near bottom layer from 15 to 7°С.…”

A hardware-software complex that allows synchronous measurements of hydroacoustic noises and signals, the temperature, and the pressure at a specified point and provides transmission of theses char acteristics via a radio channel and their recording in a shore based analytical center is described. The offshore part of the complex includes a GPS receiver for testing the location during drift. The results of an experimen tal approbation of the complex during acoustic thermometry of a water area in the Vityaz bay of the Posiet gulf in the Sea of Japan are presented.

“…The maximal arrival times were recorded during the same hours. This is attributable to the fact that the travel times of pulses, multiply reflected from the bottom and the surface, are sensitive to changes in depth so that the high and low tide levels can be found from variations in the travel time amplitudes [3].…”

“…Finally we compared these data to the GPS determinations and estimated the error. Details of engineering and methodological features of the technology of navigation measurements are described in [3,4]. Figure 4a illustrates the time dependence of errors in determining the coordinates and distances between the receiving system and emit ters 1 and 2.…”

The paper describes the results of testing experiments for solving problems of thermometry and positioning of an autonomous underwater vehicle (AUV) in the Korean Strait in a shallow sea with less than 10 m of water. The studies were conducted on acoustic tracks up to 615 m long, sensed with complex phase shift keyed signals with a centeral frequency of 2500 Hz. Under field experiment conditions, it was shown that the resolution of the structure of pulse responses makes it possible to sense temperature changes less than one degree and to secure positioning of the AUV with an accuracy better than 1 m when operating in the near bottom layer.

“…At the second stage of the experiment, we studied the possibility and precision of the solution of naviga tional problems for underwater objects at such shallow depths. For this purpose we used a mobile hardwaresoftware complex with two sources of navigational sig nals and an imitator of a submersible receiver path described in detail in [3]. In addition, source no.…”
