Dynamically Tuned Gyroscope

This dynamically tuned gyro is designed fordynamical positioning and orientation inthe drilling field, with small dimension, light weight, and high working temperature, was mainly used in borehole gyro survey tools, wellbore logging tools, and many other system for north seeking or orientation. No. Parameters Performance Indicator Unit 1 Random Drift ≤0.8 °/h 2 Day by Day Drift ≤1.5 °/h 3 Drift Caused by Axial Mass Unbalance ≤15 °/h/g 4 Drift Caused by orthometric Acceleratio
