Book Description
A limiting factor in realizing the ultimate sensitivity and associated system accuracy of the more advanced inertial guidance instrumentation is the adverse influence of earth motions on performance. Motions of concern to inertial guidance testing and operations are categorized as propagating and non-propagating. Propagating motions include earth background noise and seismic events while non-propagating motions include local and regional tilts, earth tides, polar wobble, irregularities in earth rate, and precession. Motion measurement philosophy and instrumentation are discussed. (Author).

Book Description
This bibliography lists all AFCRL in-house reports, journal articles, and contractor reports issued during the reporting period. The DD Form 1473 (Document Control Data - R & D) for each publication is included. In Part I, the 1473's for in-house reports are arranged numerically by the series in which they were issued: in Part II, the 1473's for journal articles are arranged alphabetically by author; in Part III, the 1473's for contractor reports are arranged alphabetically by corporate author. For cross-reference purposes, an index is included, listing the publications numerically by the AFCRL document number.

Book Description
A siloed missile facility was occupied over a fortnight for the purpose of determining site related limitations for conducting a long-term geokinetic study. The study focused on the ground-silo-missile mount transmissibility characteristics and the field evaluation of prototype hardware. Broadband motion measurements were made of the effects of near-site loading, explosive generated motions, and environmental motions peculiar to the site. Results are presented in spectral formats. Study objectives have been met; the implementation for a long-term geokinetic siloed missile study is practicable. (Author).
