ABSTRACT

An effective development of underground space is impossible without the use of modern systems of underground navigation. And the high-precision inclinometric survey is one of the main problems of such systems, as well as the complicated systems of drilling rigs, which are usually used in the construction of oil and gas wells. As a result of research described in the paper the authors scientifically prove a necessity of new special indices of geomagnetic activity introduction. Also the algorithm of their calculation and its programming realization are suggested and described. Besides the paper is considered with description and analysis of results of Ierr/Derr-indices observation, which are used as a theoretical basis for improving methodical and metrological supplement of inclinometric surveys both in applications of underground and marine navigation. As a result the authors proved, that it is expedient to calculate and control suggested here special Ierr/Derr-indices of geomagnetic activity as well as to continue their further research of both theoretical and empirical characters. This research first of all is connected with forecast and characteristics of these indices distribution on the Earth’s surface, in its interior, and near-Earth space.
