GS-30 12-Channel Electric Receiving Station

The GS Series is a new-generation, high-performance receiver platform built for the next wave of electrical exploration, covering methods such as high-density electrical resistivity tomography (ERT), induced polarization (IP), self-potential (SP) and controlled-source audio-frequency magnetotellurics (CSAMT). Designed around high channel density, a wide dynamic range and low-noise synchronous acquisition, a single main unit can connect more than a thousand electrodes; together with distributed cable heads it delivers large-scale 2D/3D resistivity tomography, making it suitable for deep mineral exploration, geothermal and oil & gas prospecting, fine-scale detection of urban underground space, major engineering geological surveys and long-term online monitoring.

Product Overview

Functions

The GS Series supports synchronous acquisition across the SP/ERT/IP/CSAMT methods. Built on a modular multi-channel architecture, it spans three models: the portable GS-5 (48 channels), the vehicle-mounted GS-10 (96 channels) and the base-station GS-20 (192 channels). It provides GPS/BeiDou timing synchronization, 4G/wired remote monitoring, mobile APP acquisition and Geometa cloud platform data management, and works with DigSpace for waveform viewing, automatic bad-point removal, online inversion and 3D visualization.
