Abstract

The paper describes the development of a new small-size seismic module (SM-3MU) whose characteristics are close to those of SM-3 seismometers. The module operates as a velocimeter with an electronic amplifier, the frequency range is from 0.5 to 40 Hz, the resolution is 10–9 m/s at a frequency of 1 Hz, the dynamic range is about 130 dB, and the conversion factor is 2000 V s/m. The module can be used in one- (vertical) and three-component seismometers for pedestal-based, borehole, and seafloor applications. Draft design and engineering documentation is produced. Three module prototypes were manufactured to explore the characteristics of the module and carry out performance tests. The results of the study and tests showed that the characteristics of the module meet all requirements. Consequently, R&D efforts should move in this direction, enabling the manufacturing of new seismometers based on this module.
