Small-sized radio-electronic digital module for building a nodal seismic system interacting with a UAV

Digital autonomous seismic systems (nodes) have become significantly widespread in recent years. The disadvantage of such systems is the inability to control the quality of the data received. Sharing the nodal system with drones allows for data quality control while maintaining the inherent advantages of nodal systems, such as flexibility in use and reliability. The work presents the result of creating a specialized digital node intended for joint use with drones. A molecular-electronic geophone with an extended operating frequency band of 1-300 was used as the primary sensitive element; the digital system provides autonomous high-bit recording of seismic data, transmission of data blocks to control their quality to drones and auto-calibration of recording channels.
