Abstract

Increasing demand for the space operations, space industry turns its face to cost effective solutions. Small satellites, due to their size and cost, are receiving interest from many organizations. Two of most common sensors that are being used in nanosatellites are magnetometers and sun sensors. In this work, magnetometer and sun sensor measurements are fused together with the TRIAD algorithm to produce body angle estimation. Combining with gyroscopes measurements, an Extended Kalman Filter is used to estimate body angles, angular velocities, gyroscope and magnetometer biases.

用于卫星姿态估计和传感器校准的TRIAD辅助EKF

对空间操作的需求不断增加，航天工业转向具有成本效益的解决方案。小型卫星由于其体积和成本，正受到许多组织的兴趣。纳米卫星中最常用的两种传感器是磁力计和太阳传感器。在这项工作中，磁力计和太阳敏感器的测量结果与TRIAD算法融合在一起，产生体角估计。结合陀螺仪的测量，利用扩展卡尔曼滤波估计物体角度、角速度、陀螺仪和磁力计的偏差。

期刊介绍： WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
