Abstract
Devices, systems, and methods for stabilizing a gyroscopic sensor include bearings supporting a MEMS-type gyroscope located in a shell. The shell rotates around a secondary shaft connected to an extension arm of a primary shaft. A biasing element pre-loads thrust bearings on either side of the shell against the extension arm, which can limit motion of the shell during operation of the sensor, thereby improving measurements made by the sensor.
