空军为满足先进战斗机的需求已提出高准确度定时频率源和精密惯性导航系统的要求。作者曾提出一种采用多频环形激光陀螺仪(RLG)同时作为陀螺仪和钟的方法。这种器件采用带附加检波器的多频环形激光陀螺,该检波器用于检出583MHz的拍频,并相应地配上必要的电子部件,以产生5MHz的钟信号。已完成两套环形激光陀螺的试验工作。第一套环形激光陀螺在低速旋转时并不起陀螺仪的作用。稳定度数据在lms与200ms之间是较好的,但时间更长则开始变坏。第二套环形激光陀螺起陀螺仪的作用,不过来曾在试验中作过相应的测试。频率稳定度达到4.6×10~(10)/lms;3.4×10~(-10)/10ms;8.7×10~(11)/0.1s;1.6×10~(10)/1.0s;4.5×10~(10)/10s;4.8×10~(-9)/100s。从lms到200 ms的数据主要受量子系统限制。长期稳定度变坏显然是由法拉第转子的温度漂移所引起。建议采用补偿法以改进准确度。环形激光陀螺钟是一种传递型频标,因而在使用前必须调节到参考频率源的频率上。目前可按全球定位系统(GPS)、联合作战情报发布系统(JTIDS)、雷达技术或直接连接到一时间标准等办法作参考来调节环形激光陀螺钟。
To meet the needs of advanced fighter jets, the Air Force has proposed the requirements for high accuracy timing sources and precision inertial navigation systems. The authors have proposed a method that uses a multi-frequency ring laser gyro (RLG) as both a gyroscope and a clock. The device uses a multi-frequency ring laser gyro with an additional detector for detecting a beat frequency of 583 MHz and matching the necessary electronics to produce a 5 MHz clock signal. Has completed two sets of ring laser gyro test work. The first ring laser gyro does not function as a gyroscope at low speeds. Stability data between lms and 200ms is better, but over time it begins to deteriorate. The second ring laser gyroscope gyroscope role, but in the experiment had made the appropriate test. Frequency stability of 4.6 × 10 ~ (10) /lms; 3.4 × 10 ~ (-10) /10ms;8.7 × 10 ~ (11) /0.1s;1.6 × 10 ~ (10) /1.0s;4.5 × 10 ~ (10) /10s;4.8×10~ (-9) / 100s. Data from 1 ms to 200 ms is mainly limited by the quantum system. Long-term stability deterioration is apparently caused by the temperature drift of the Faraday rotors. Recommended compensation method to improve accuracy. Ring laser gyro clock is a transfer-type frequency standard, and therefore must be adjusted to the frequency of the reference frequency source before use. Ring laser gyro clocks can now be adjusted by reference to GPS, JTIDS, radar technology, or directly to a time standard.
