1. Device for measuring and assessing the mutual alignment of bodies, with at least one optical gyro enclosed within a housing, wherein the housing has means for manually transporting the housing and for holding the housing in place on a body whose state of alignment is to be determined, and wherein the device is provided with transmission means for wirelessly receiving or exchanging at least one of data, commands and other information with an externally arranged control or a higher-level supervisory computer, wherein the externally arranged control or higher-level supervisory computer has means for performing an averaging measured value acquisition to ascertain the spatial orientation of the bodies or the device in a time-sequential manner with a measurement frequency which excludes the following frequency ranges or values, integral fractions or integral multiples thereof:
the range from 47 to 53 Hz or from 56 Hz to 64 Hz
the range of a technical line frequency
a rotational or oscillation frequency of a machine integrated into the bodies to be measured
a frequency band which is located in the immediate vicinity of a mechanical acceleration frequency which occurs at a selected measurement site with above average intensity or which can appear there.
