2. Calculation of the Depth of Diving of the Underwater Vehicle. N. A. Nesterov, R. A. Andreyuk. – Navigation and hydrography. – 2018. – No. 52. – p. 14–21.

Determining the depth in the process of diving, swimming and working in the water column of the underwater vehicle (UV) is an important navigational task. Accurate knowledge of the depth, the third spatial coordinate, provides not only navigation safety UV, but also high-quality binding of the data. Therefore, the problem of choosing the optimal solution of this problem and developing the appropriate algorithm is very significant. In JSC "Marine Navigation Systems" was conducted study and developed the algorithms for implementation in computer software of the depth.

Keywords:   underwater vehicle, hydrostatic pressure, density, salinity, temperature, sound velocity, immersion depth.
