摘要

上一代消费级MEMS惯性传感器具有几个独特的功能,使其在专业导航应用(如与先进小型无人机的姿态确定相关的应用)中也具有兴趣。当使用低成本消费级MEMS陀螺仪时,出现了几个优点,例如减轻重量,紧凑的配置,低功耗和易于与电路板集成。相反,在精度方面确定了一些缺点,因为总体误差比工业级传感器差一个数量级以上。为了提高基于商用级MEMS陀螺仪的惯性单元的精度,本文利用了冗余技术。它包括采用倾斜传感器配置,即在正多面体的面上放置定义数量的传感器。这种配置保证了放置在多面体相对面上的传感器偏差的自校准。为了测试所提出的方法,采用了ST Microelectronics™的世界上密度最大的传感器板SensorTile™。试验结果表明,通过对同一轴的多次测量进行平均,可以提高飞行姿态确定的整体精度水平。

Advanced Low-Cost Integrated Inertial Systems with Multiple Consumer Grade Sensors
Last generation consumer grade MEMS inertial sensors have several distinctive features that make their use of interest also for professional navigation applications such as the ones related to attitude determination of advanced small drones. Several advantages arise when using low-cost consumer grade MEMS gyros, such as reduced weight, compact configuration, low power consumption and easy integration with electronic boards. Conversely, some drawbacks are determined in terms of accuracy, since the overall error is more than an order of magnitude worse than industrial grade sensors. To improve the accuracy of inertial units based on commercial grade MEMS gyros, redundancy is exploited in this paper. It consists in adopting a skewed sensors configuration, i.e. a defined number of sensors placed on the faces of a regular polyhedron. This configuration guarantees the self-calibration of the bias of sensors placed on opposite faces of the polyhedron. To test the proposed method, the world's densest sensor board, the SensorTile™, by ST Microelectronics™ has been adopted. Test results show that, by averaging multiple measurements about the same axis, the overall level of accuracy in flight attitude determination will be improved.
