Abstract

In this letter, we present a novel algorithm to calculate attitude with data measured by a magnetometer and an accelerometer. The calculation error for the attitude angles is not affected by the external motion acceleration parallel to the plane, which is composed of the gravitational field and geomagnetic field. The simulation and actual experimental results have revealed that the algorithm improved the accuracy of the attitude estimated in roll or pitch angles for different flight directions compared with the arc-tangent attitude solution method. Our algorithm provides a new model for attitude estimation through a vector observation method and has excellent prospects in real-time, satellite-free geomagnetic navigation.

实时地磁导航的组合姿态确定

在这封信中，我们提出了一种利用磁力计和加速度计测量的数据计算姿态的新算法。姿态角的计算误差不受由重力场和地磁场组成的平行于平面的外部运动加速度的影响。仿真和实际实验结果表明，与反正切姿态求解方法相比，该算法提高了不同飞行方向滚转角或俯仰角姿态估计的精度。我们的算法通过矢量观测方法为姿态估计提供了一个新的模型，在实时无卫星地磁导航中具有良好的前景。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
