NAVIGATION AND HYDROGRAPHY №44/2016
Possibilities of Creating the Correction Systems using the Magnetic Field for Ship Navigation Complexes. P. I. Maleyev. – Navigation and Hydrography. – 2016. – No. 44. – Р. 9–15.
The specific features of the Earth¢s magnetic field and artificial magnetic bench marks and possibilities of their registration on the marine moveable objects are considered. The advantages of using these fields when creating the correction systems for ship navigation complexes are evaluated. The results of experimental and field explorations of the created mock-up versions of such systems are presented.
Key words: navigation complex, correction system, the Earth¢s magnetic field, ship(borne) magnetometric system, magnetic bench mark.
Place of Gravimetric Equipment among the Ship Navigation Aids and Prospects of its Development. P. I. Maleyev. – Navigation and Hydrography. – 2016. – No. 44. – Р. 16–20.
The gravimetric equipment plays an important part in increasing the accuracy of ship navigation aids. However, the present-day level of its development does not meet the current requirements, and what is more important, the long-term requirements. To increase the accuracy of gravimeters by reducing their instrumental errors, it is expedient to use, as a sensitive element, not the deformation of the resilient bodies (springs. etc), but suspension of the tested mass in electrostatic and magnetic fields. To reduce the methodical errors due to Eotwos effect it is expedient to use the advanced heading indication systems and devices measuring the absolute speed (which, in particular, use the Earth¢s magnetic field and artificial magnetic bench marks).
Key words: navigation, gravimetric devices, gravity acceleration, deviation of plumb line, inertial navigation system, errors.

Hydrolocation Monitoring of Bottom Features. N. A. Nesterov, V. V. Guzivaty, N. A. Naumenko. – Navigation and Hydrography. – 2016. – No. 44. – Р. 30–37.
The monitoring of the individual bottom features is location extremal important in the study of relief-forming processes in lake Ladoga. The location and movement of small forms of the relief (small stone clusters, single boulders and ridges) allow to describe the dynamics of processes and to assess their degree of intensity in the zones of seismic activity, faults and potential landslide movements. The main difficulty of monitoring the small-size objects on the bottom is in accurately determining their location, the error magnitude is often far greater than the size of observed objects and therefore does not allow to identify reliably and trace the dynamics of their relocation. It is proposed to solve this problem by the method of binding the objects uniquely identifiable on the sonar image, relative to each other.
Key words: monitoring, bottom features, side scan sonar, root mean square error, sonar image.
The Method of Evaluating the Synchronization of Tides with Movement of the Moon and the Sun. Y. N. Zhukov, E. V. Fedorova. – Navigation and Hydrography. – 2016. – No. 44. – Р. 38–46.

It is shown that the tidal variations in diurnal, semidiurnal and quarterdiurnal intervals of periods are synchronized with the visible movement of the Moon and the Sun to a different degree.
Key words: tides, synchronization, the Moon, the Sun.
