Abstract:
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.
