Ways to Improve the Automated System Providing the Navy with Digital Cartographic Information (DCI). V. A. Titlyanov, A. A. Yakushev, M. Y. Smirnov. – Navigation and Hydrography. – 2015. – No. 42. – Р. 7–11.

The principles of structure of the Navy DCI Automated Support System, its operation, the problem issues of creating the cartographic server for ships and vessels of the Navy are considered. The main technical requirements to its development and creation are formulated.

Key words: cartographic server, geoinformation systems, automated systems, regional center, cartographic information, electronic navigation chart (ENC), space databases.

Present-Day Approaches to Solving the Problems of Navigation Safety Provision for Vessels and Ships in the Arctic. P. G. Brodsky, Y. V. Rumyantsev, A. N. Lukin. – Navigation and Hydrography. – 2015. – No. 42. – Р. 12–19.

It is shown that at the current stage of development of means and methods necessary to provide the navigation safety for vessels and ships in the Arctic, the employment of virtual aids to navigation, aids of vessel traffic control based on the automatic identification systems and low-orbit satellites is becoming the urgent problems of today.

Key words: virtual fixing the vessel¢s position, accuracy standards of ship navigation, virtual aids to navigation, automatic identification systems, vessel traffic control systems.

Revealing the Perspective Directions of Development for Means and Methods of Sea Bottom Investigation Based on the Patent Information Analysis. P. G. Brodsky, V. P. Lenkov, A. B. Fedorov. – Navigation and Hydrography. – 2015. – No. 42. – Р. 20–27.

The main provisions of approach used to determine the scientific technical level of innovation solutions of patent and its innovation potential are presented. The results of evaluation development of the means and methods used to investigate and survey the bottom relief based on the analysis of some patents of the “GNINGI” OJSC specialists, are generalized and presented.

Key words: innovation development, means and methods of investigation and survey of sea bottom relief, scientific-technical level of innovation solutions of patent, innovation potential of patent, patent information.

Noninterpolation Method of Determining the Limits of Dangerous Sea Bottom Areas on Charts. A. M. Abramov. – Navigation and Hydrography. – 2015. – No. 42. – Р. 27–31.

The method of determining the limits of navigationally dangerous sea bottom areas using the charts is considered. In this method the interpolation of depths shown on the charts is not required. It is shown that to determine such limits it is possible to use the representation of the submarine relief segmented into monochromatic sections.

Key words: chart, bottom relief, navigational depth, Morse-Smale cells, separatrixes, critical points.

State and Prospects of Development for Meteorological Satellite Systems. A. B. Lebedev, D. M. Karavayev, G. G. Shchukin. – Navigation and Hydrography. – 2015. – No. 42. – Р. 32–39.

The overview and analysis of the current state and prospects for development of domestic meteorological space systems are presented. The technological aspects and ways to improve the quality of the operational use of satellite hydrometeorological information are discussed.

Key words: validation of remote sensing meteorological products, calibration of satellite data, the meteorological space system, the meteorological space complex, meteorological satellite, ground special complex, geographically distributed state space monitoring system.

The Weather Forecast. What is it? Y. N. Zhukov. – Navigation and Hydrography. – 2015. – No. 42. – Р. 39–45.

The weather forecasts are based on taxonomic type regularities and are not the cause-and-reason conclusions. At present, when developing the forecasts, it is considered that the values of meteorological values reflect the laws of atmosphere changeability. It is shown that this point of view does not take the cycle of matter and energy in the atmosphere into account. The completely new direction of development of forecasts based on revealing the latent noncasual regularities of cycles of the matter and energy is suggested.

Key words: weather forecasts, classification of forecasts, logical, qualities of forecasts.

Wind as a Notion. Y. N. Zhukov. – Navigation and Hydrography. – 2015. – No. 42. – Р. 46–51.

Wind is the cycle of air of the atmosphere. The everyday and meteorological notions of the wind are compared. The interval description of the wind is suggested.

Key words: wind, notion, definition, forecast.
