| 1. A seismic data acquisition system, comprising: a plurality of sensors arranged to measure translation movements in a medium
with three independent spatial components and an independent rotation component around each of the three independent spatial
components, thus forming a system having six components, namely said three independent spatial components and said independent
rotation component around each of the three independent spatial components,
wherein the plurality of sensors comprise six sensors of the translation motion type,
wherein each of the six sensors of the translation motion type measures a translation along its own single sensitive axis,
and wherein the six sensors of the translation motion type are accommodated in a module and are arranged in respect of position
and direction, so that a matrix linking a vector m representing the six translation movements measured by said six translation
motion type sensors, and a vector v representing actual movements of the medium and having said six components, namely said
three independent spatial components and the three independent rotation components around each of the three independent spatial
components, is invertible.
