在手短期订单超2024全年营收。 作者 | 贝壳XY 编辑 | 小白 "惯性"，熟悉不？初中物理必考的知识点。而惯性传感器就是利用惯性技术、通过内嵌的微机械芯片 （MEMS）和专用控制电路芯片（ASIC）来感知物体的运动姿态和轨迹，其显著特点在于不依赖于 外部信息、也不向外部辐射能量。 再经过下游模组与集成，为终端用户实现导航定位、姿态感知、状态监测、平台稳定等功能。 举个最常见的例子，当汽车驶入隧道导致手机丢失GPS信号时，仍能凭借惯性传感器的持续感知继续 导航。 陀螺仪和加速度计是两大主要惯性传感器类型，前者用于感知物体运动的角速率，后者用于感 知物体运动的线加速度，二者辅以时间维度进行运算后可得出物体相对于初始位置的偏离，进 而获得物体的运动状态。 所以说，看似 小小一个MEMS惯性传感器，其应用却极为广泛：上至卫星雷达、航空航天航海等战 略级领域，下至消费电子、人形机器人、低空经济、智能驾驶、无人机、石油勘测等工商业领域，几 乎覆盖了所有当下热门概念。 ...
