Abstract : A seismic survey of an area scheduled for use as a single-degree-of-freedom floated rate-integrating gyroscope test station is described. Evaluation is made of long-period tilt and short-period vibrations which are functions of both cultrual activity and local disturbances. Errors introduced into a single-degree-of-freedom floated rate-integrating gyroscope due to cultural activity and local disturbances are presented in graphical form. Short-period angular and translation vibrations over a frequency range up to 5000 cps are defined. Calculations are made to determine the total maximum errors which could be introduced into a single-degree-of-freedom floated rate-integrating gyroscope by angular vibrations and translation acceleration. It is shown that the largest single error occurs in the frequency range from 1 to 10 cps. This error, based on the limit of resolution of approximately 55% of the total contributing error. (Author)
