| 摘 要： | 半球谐振陀螺仪(HRG)是一种高精度、高可靠、长寿命的新型固体振动陀螺仪。温度变化会影响半球谐振陀螺的漂移、零偏等性能指标。为减小这种影响，该文通过研究分析半球谐振陀螺的温度特性，设计了温度补偿电路。采用温度补偿电路后，半球陀螺漂移精度从0.05 (°)/h提高到0.03 (°)/h。

| Abstract: | Hemispherical resonator gyro(HRG) is a new solid state vibrating gyro of high precision, high reliability and long life. The change of temperature will influence the drift and bias of HRG. The temperature characteristic of HRG is analyzed and a temperature compensation circuit is designed to reduce the interference. By using the temperature compensation circuit, the drift performance of HRG is improved from 0.05 (°)/h to 0.03 (°)/h. |
