The GSK-166, now a legacy product, was an innovative uniaxial linear shaking table, which was based on an industrial high accuracy linear displacement driver, providing a large force driving capacity over a large displacement. Due to the strong axial magneto-guidance, even large or unbalanced loads could be tested. The ingenious design of the GSK-166 enabled swapping the table from horizontal to vertical operation within minutes.

GeoDAS software controlled the GSK-166 via its scripting capability, which provided full control over the generated motion while the shake table driver executed the required dynamic displacement within the table displacement limits. Almost every imaginable waveform was possible, such as recorded earthquakes, sine-sweeps or synthetic signals. This allowed a large variety of different applications. Field calibration of sensors or seismic qualification of stand-alone recorders could then be done in-house.
