The seismic survey is conducted using the ISSD (In-Motion Geophysical Data Recording) technology, developed by GEOTEK. Alongside traditional elastic wave sources, the method utilizes Yenisei N-20 impulse sources. Sensors mounted on mobile platforms detect the waves as they continuously move along predefined trajectories at a set speed, with onboard receivers recording the collected data.

Typically, geophysical data in seismic surveys is gathered from stationary positions. However, this approach is often hindered by infrastructure such as roads, railways, pipelines, power lines, and residential areas.

To eliminate interference and improve data quality, scientists made the sensor operation autonomous and synchronized it via timing systems. According to the developers, the number of sensors can be virtually unlimited, allowing for a higher volume of data collection in a shorter time and significantly increasing seismic survey efficiency.
