根据天基反导弹合同(SDI 合同),采用光纤陀螺和小型微细加工的单晶硅加速度计两种新技术研制出一种轻重量的小型惯性测量装置(IMU)。本文介绍了这两种新型惯性仪表的工作原理。这两种仪表使 IMU 具有高灵敏度、宽频带、低噪声、轻重量和快速反应等特点,适合于 SDI、军用和商业等多方面的应用。采用三个微型光纤陀螺(FOG)和三个硅加速度计组成的一个可供飞行的 IMU试验模型已经研制成功。这个试验模型在实验室内进行了静态和动态试验,试验数据较好地满足了性能要求。本文预测了下阶段的工作:进一步小型化,并将其推广到导弹和飞机的罗盘/姿态与航向基准系统(AHRS)等多方面的应用。
According to the space-based anti-missile contract (SDI contract), a new lightweight inertial measurement device (IMU) was developed using two new technologies: fiber optic gyro and small micro-machined silicon accelerometer. This article describes the operation of these two new inertial instruments. These two instruments make IMU high sensitivity, wideband, low noise, light weight and fast response, suitable for many applications such as SDI, military and commercial. A flying IMU test model using three miniature fiber optic gyros (FOG) and three silicon accelerometers has been developed. The experimental model in the laboratory static and dynamic tests, the experimental data to better meet the performance requirements. This article predicts the next phase of work: to further miniaturize and extend it to various applications such as the Missile and Aircraft Compass / Attitude and Heading Reference System (AHRS).
