the Earth's Gravitational Field. E. S. Zubchenko. –
Navigation and Hydrography. – 2015. – No. 39. – Ð. 16–24.
The method of requirements substantiation to digital
model of the Earth's gravitational field for provision of high-accuracy
autonomous navigation is considered. The method is based on the use of spectral
densities of model and transfer function of inertial navigation system for
calculation of root-mean-square error in determining the position co-ordinates
by the navigation complex depending on the duration of autonomous navigation.
Results of modelling the error for various values of field model parameters
confirming the possibility of obtaining the practical results of evaluation are
presented.
Key words: Digital model of the Earth's gravitational field,
function of spectral densities of residual anomalies of gravitational field,
function of spectral density of model, inertial navigation system, transfer function
of navigation complex, error of calculation of position co-ordinates.

– Navigation and Hydrography. – 2015. – No. 39. – Ð. 25–32.
Development of oil and gas fields of the Arctic seas
of the Russian Federation is the most complex scientific, technical and
organizational-economic problem; it belongs to dangerous kinds of economic
activities. Presence of icebergs in water areas of sea deposits generates the
special risks caused by possibility of collision of an iceberg with objects of
arrangement. The results of computer simulation scenarios of icebergs
interaction with offshore production platforms are presented. Risks of such
interactions are estimated. It is shown that the proposed technology for
probabilistic analysis of dynamic models can significantly reduce the degree of
uncertainty in the assessment of the danger of icebergs in the design of
offshore structures.
Key words: Oil and gas field, the Arctic region, management of ice
situation, iceberg, offshore production platforms.
