近来在波音747飞机上成功的飞行试验证明,半球谐振陀螺可以与惯性级[0.01(°)/h]及环形激光陀螺相比拟。为了增加半球谐振陀螺产品的种类,Delco电子仪器公司正在开发两种小型半球谐振陀螺,这两种产品是专门为了低成本惯性测量装置和中成本惯性导航设备而设计的。介绍了小型半球谐振陀螺的惯性级和战术级传感器及其辅助电子线路的基本设计。为降低电子线路的成本并保持1ppm(10~(-6))的精度,重点介绍了数字控制和处理技术。由于低成本惯性测量装置的产品具有很强的竞争性,所以有必要将环形激光陀螺和光纤陀螺传感器与新型半球谐振陀螺传感器对照进行比较。
Recent successful flight tests on Boeing 747s have demonstrated that hemispherical resonant gyros can be compared to inertial grade [0.01 (°) / h] and ring laser gyros. To increase the variety of hemispherical resonator gyroscopes, Delco Electronics is developing two small hemispherical resonator gyros, which are specifically designed for low-cost inertial measurement devices and medium-cost inertial navigation devices. The basic design of inertial and tactical sensors and their auxiliary electronic circuits for small hemispherical resonator gyroscopes is introduced. To reduce the cost of electronic circuits and maintain 1 ppm (10 -6) accuracy, the emphasis is placed on digital control and processing techniques. Due to the high competitiveness of low cost inertial measurement devices, it is necessary to compare ring laser gyro and fiber optic gyro sensors with the new hemispherical resonator gyro sensor control.
