Gyro case rotation monitoring is an important technique used to improve the system accuracy and to decrease the gyro drift in a stabilized gyro compass.The structural features,basic operating principle,signal flow and stabilized loop of the system were described in detail;the ways of selecting rotational speeds were further studied;an error analysis was run for the system;and the rotational speed of a gyro case under typical conditions was established through calculation.It is concluded from the results and discussions that the gyro case rotation monitoring technique can be used to effectively control the gyro drift and improve the accurary of a gyroscope by 2 or 3 orders of magnitude.
