Recorder / DSS CUBE
The DSS CUBE recorder (201 units) is a stand-alone 1-channel digital data recorder. It is characterized by a small and light-weight design and extremely low power consumption. This means that it runs on 2 D-cell batteries for up to 3 weeks (depending on temperature etc.). High timing accuracy is provided by build-in GPS. Data are accessible via USB-based download. Main field of application are controlled-source seismic field experiments.
The DSS CUBE recorder is a GFZ development, developed at Section 2.2 “Geophysical Imaging” and the “Geophysical Instrument Pool Potsdam” (GIPP). Credits belong to Trond Ryberg, Mike Hönig and Karl-Heinz Jäckel who initiated and put forward the project. The development was completed in Summer 2009, the first 14 units were manufactured in September 2009. 210 units of this type are available (supply on loan) through the GIPP since February 2010. (more information)
Recorder / DATA-CUBE3
The DATA-CUBE3 recorder (800 units) is a stand-alone 3-channel digital data recorder characterized by a small and light-weight design and extremely low power consumption. It is an advancement of the DSS CUBE recorder developed at the GFZ. Internal and external batteries can be used thus making it a versatile instrument for both controlled source applications and passive seismics. High timing accuracy is provided by build-in GPS. A version with external GPS antenna and solely external battery is also available (163 units). Data is accessible via USB-based download. (more information)
Recorder / GEODE
The Geode™, made by Geometrics, is a multi-channel digital recording system. The system consists of 24-channel recorders linked together by an interface cable using TCP/IP, and finally linked via interface box to a common PC LAN socket. Each recorder box is feed by a 260 m geophone spread cable (GIPP ordered two 130 m cables instead) having takeouts for PE-7 clips every 10 m.
The information is stored first in the recorder box (volatile RAM!!), and then transmitted to the PC on request.
Parameter SetUp, Line Check, and Data Retrieval are controlled via PC.

Recorder / SUMMIT
The SUMMIT, made by Deutsche Montan Technologie (DMT), is a multi-channel digital recording system. The system consists of single-channel recorders (Remote Units, RU) connected along a two-wire Data Link, and a Central Unit (PC-board or workstation). Sensor adaptors are available for geophone chains (PE-7 connector) and for the S_ MARK L-4C-3D geophone.
The information is stored first in the Remote Unit on nonvolatile RAM, and then transmitted to the Central Unit on request.
Remote Unit ID Numbers are set by a SUMMIT handheld terminal. Parameter SetUp, Line Check, and Data Retrieval are controlled from the Central Unit.
Long Data links require Repeater Units (RP) every 250 m. All Repeater Units also implement the function of Line Distributor Units.
An 'intelligent RP' is currently tested. It will make available the same remote control functions as given for the Remote Units (RU).

The "Geophysical Instrument Pool Potsdam" (GIPP) of the GFZ has aquired a fiber-optic gyroscope which allows the highly accurate orientation of geophysical sensors. This gyroscope produced by the company IXSEA allows the orientation of sensors (relative to Earth's rotation axis) with a typical accuracy of 0.1° (secant latitude). The orientation of sensors using a magnetic compass usually suffers from magnetic deflections by metal parts (e.g. in buildings) and the magnetic declination which is locally and temporary variing. The use of the fiber-optic gyroscope avoids these pitfalls. The exact orientation of seismometers is for example essential for the analysis of seismic anisotropy.
