Abstract
Background. Gravimetric monitoring is used to study changes in the Earth’s gravitational field. Even minor variations in this quantity can carry important information about the presence of underground structures, minerals or tectonic processes. A significant part of the gravimetric equipment in Ukraine is represented by analog gravimeters which, despite their high sensitivity and reliability, have a number of design limitations associated with the manual method of control and reading of measurement results. In such systems, there is a significant influence of the human factor, the need for the constant presence of an operator near the device and the complexity of performing long series of measurements. In this regard, a promising direction is the modernization of existing ana-log gravimeters by implementing automation and remote-control systems, which allow to increase the accuracy and reproducibil-ity of gravimetric measurements.
Methods. The research methodology involved the modernization of an existing gravimetric instrument without introducing structural modifi
cations to its sensitive opto-mechanical system through the integration of external automation tools, remote control capabilities, and real-time data transmission.
Results. A comprehensive project for the modernization of analog gravimeters was developed, ultimately resulting in the creation of a gravimetric complex comprising a set of hardware and software components designed for the measurement, recording, and analysis of variations in the Earth’s gravitational field. The gravimetric complex provides remote reading of instrument indications and con-trol of the measurement process. The main concept of the project was to preserve the original mechanical and optical components of the gravimeter without structural alterations while supplementing them with external automation technologies. This approach enables the continued use of existing high-precision analog instruments, significantly expanding their functionality and improving operational efficiency. Experimental validation of the gravimetric complex confirmed the operability of the developed system and demonstrated a reduction in the variability of measurement results compared with the conventional manual measurement method.
Conclusions. The implementation of a remote data acquisition and automated control system in analog gravimeters substantially enhances their operational capabilities. The proposed approach improves the accuracy and reproducibility of measurements, minimizes the influence of the human factor, and enables remote monitoring of the observation process. The practical value of the development lies in providing a universal solution for upgrading existing gravimeters without interfering with their internal structure, thereby creat-ing opportunities for the deployment of automated gravimetric observations and the integration of such instruments into modern information and measurement systems.
