Production testing procedures are recommended for evaluation of precision gyros used to stabilize inertial platforms in a ballistic missile environment. It is recommended that tumbling tests be used for measurement of the drift coefficients g-insensitive, g-sensitive, and g2sensitive drifts that the long-term stability of the drift coefficients be measured on sample gyros selected from the production line and on gyros recycled from systems in the field and that by means of three cogging tests, the shortterm repeatability of the drift coefficients be measured. Short-term is defined for the purpose of this study as a period comparable to missile flight time. This study does not recommend usage of the 24-hour servo tests for applications of the ballistic missile type.
