Design of temperature control system of hemispherical resonant gyroscope
Dianzi Jishu Yingyong, 2021 Thermal drift is a key factor in gyroscope precision. To ensure the output accuracy of the hemispherical resonant gyroscope, a temperature control system for the hemispherical resonant gyroscope has been designed in this article. It provides gyroscope with constant temperature to reduce the influence of temperature and inhibit the thermal drift.
