The gDAS32 Distributed Array system

High-resolution, modular, and easy-to-deploy acquisition system for IP, MT, CSEM surveys and more.

High Resolution, Precise Timing & Low Internal Noise

Dual 32-bit ADC's provide high signal quality with timing synchronization provided by internal GPS-PPS, for excellent phase precision up to sampling rates of 32 kHz.

Programmable autonomous acquisition schedules

Through programmable schedules, synchronous acquisition is achieved across widely distributed arrays. Intra-array communication is not required.

Flexible deployment for multi-method acquisition

the gDAS-32 supports multiple geophysical methods — including IP, CR, MT, CSAMT, CSEM surveys and more.

For easy operation in field, a tablet or smartphone can be used for wireless control and for data quality analysis.

Reliable and Rugged

Field-proven from high-altitude Andean peaks and humid tropical jungles in central Africa to the burning Australian Outback.

Broad Sensor and Instrument Compatibility

Fully compatible with any transmitter system, several reciever sytems and most geophysical sensors, including industry-standard induction coils:

Zonge ANT-4/6
Phoenix MTC-185U
LEMI/KMS
Geometrics

iSense

The iSense is a compact, Hall sensor, current monitor designed for any controlled source survey with any transmitter system.

It measures transmitter current (80 mV/A) to enable precise full time-series recording with any gDAS-32.

Accurate full current waveforms are essential for post-processing most controlled source datasets, including Time-Domain IP, Complex Resistivity, and CSEM.

gDAS App

The gDAS32 offers an intuitive Android app for seamless interaction with the instrument and control of geophysical data acquisition.

Through Bluetooth or extended-range radios, users can easily manage settings, monitor real-time data, and initiate time series acquisitions.

gDASPro data processing software

Survey Management & Processing

gDASPro centralizes all survey data in a single SQLite database, handling configurations, source/sensor info, time series links, and results. It guides users from initial setup to final visualizations—sections, maps, and 3D plots—in industry-standard formats like EDI, AVG, DAT and AMIRA.

Flexible Workflow

Supports manual or batch linking of data to sources and sensors

Enables editing and processing at station, line, or area level

Output-ready for inversion software
