本文概述了惯性传感器技术在当前应用中的应用，以及它在近期和远期应用中的应用前景。讨论了惯性传感器技术的发展趋势，即干涉式光纤陀螺、微机械陀螺和加速度计以及微型光学传感器。微机械传感器和改进的光纤陀螺有望取代许多目前使用环形激光陀螺仪或机械传感器的系统。新技术的成功引进主要是由成本和成本预测系统使用这些新技术。利用全球定位系统（GPS）对惯性导航系统（INS）进行外部辅助，已经开启了导航各种新的大容量应用（例如制导炮弹）的能力。这些新应用推动了对极低成本、可批量生产的传感器的需求。
This paper presents an overview of how inertial sensor technology is applied in current applications and how it is expected to be applied in near-and far-term applications. The ongoing trends in inertial sensor technology development are discussed, namely interferometric fiber-optic gyros, micro-mechanical gyros and accelerometers, and micro-optical sensors. Micromechanical sensors and improved fiber-optic gyros are expected to replace many of the current systems using ring laser gyroscopes or mechanical sensors. The successful introduction of the new technologies is primarily driven by cost and cost projections for systems using these new technologies are presented. Externally aiding the inertial navigation system (INS) with the global positioning system (GPS) has opened up the ability to navigate a wide variety of new large-volume applications, such as guided artillery shells. These new applications are driving the need for extremely low-cost, batch-producible sensors.
