Central Systems

Central Recording System (CRS) – The CRS includes the Seismic Processing Module (SPM), which is a multiprocessor PC with custom line interface cards and up to four monitors. The system offers three seismic processing modules (SPM) to accommodate a variety of survey parameters for any type of operation.

SPM Extended PCIe – Offered with extended capabilities that is perfect for most acquisition surveys with system capacity to support up to 240,000 channels.

SPM Standard PCIe – Built with high end multi-core processing technology targeted to support up to 120,000 channel counts for high-density advanced vibroseis 3D operations.

SPM Lite – The SPM Lite is a lightweight and portable substitute for the standard SPM. It supports seismic operations up to 2,000 channels real-time at 2 ms sampling.




Ground Equipment

Digital Remote Acquisition Module – A self-contained unit designed to interface with up to 12 digital channels (4x3C station, 12x1C station) that records seismic data and transmits the data digitally to the central equipment.

Digital Fiber Tap Unit – A self-contained unit that taps into a receiver line and allows connection to other DFTUs or the recording truck. Designed to interface with up to 12 digital channels (4x3C station, 12x1C station), it acquires seismic data from the digital sensors and retransmits data from the DRAMs to the central recording equipment. With built-in power supplies and hot-swappable dual battery ports, the unit also provides power-down-the-line (PDL) to multiple DRAMs.

Digital Power Supply Unit – A self-contained unit designed to interface with up to 12 digital channels (4x3C station, 12x1C station) and hot-swappable dual battery ports that sends power-down-the-line (PDL) for up to eight DRAMs and eliminates the need for a battery on each DRAM.

Cables – The cables provide the highest strength-to-weight ratio in the industry. It has over 273 Kg tensile strength per Kg weight which is lighter and stronger per Kg of cable weight than other cables offered in the market.


Testers and Chargers

Network Tester Unit – A portable, self-contained, battery-powered unit that executes functional test applications for the line equipment independent of the Central Recording System.

LED Cable Tester – An easy-to-use, handheld testing tool that provides a simple way to check the continuity of any of the conductors in a cable.
