Electrical research in geology is used quite widely and with great efficiency. The use of ready-made signal recorders for these purposes is possible, but not effective enough, since in any case, they need to be modified to provide additional functions. Such functions include the synchronization of measurements with signals from positioning systems GPS or GLONASS. This synchronization is necessary in order for the measurement results to be linked to actual space and time coordinates as accurately as possible. The same measurements taken at different times may give different results due to changes in the orientation of the Earth relative to the Sun and Moon, as well as for other uncontrollable reasons. The need to accurately determine the coordinates of the measurement is obvious. The creative team of the commonwealth of organizations, the key of which is the Siberian Branch of the Federal State Budgetary Institution of Science of the Federal Research Center “Unified Geophysical Service of the Russian Academy of Sciences”, carried out the development and initial testing of a specialized signal recorder for electrical research. The additional modification was required to eliminate the identified deficiencies. This paper reports the main technical solutions when creating this recorder, describes the modification ,and gives an example of using this recorder for field measurements. |
