Pico-satellite Autonomous Navigation with Magnetometer and Sun Sensor Data

Chinese Journal of Aeronautics 2011年第1期24卷 46-54页

作者： han ke wang hao tu binjie jin zhonghe Department of Information Science and Electronic Engineering Zhejiang University Hangzhou 310027 China

This article presents a near-Earth satellite orbit estimation method for pico-satellite applications with light-weight and low-power requirements. The method provides orbit information autonomously from magnetometer and sun sensor, with an extended Kalman filter （EKF）. Real-time position/velocity parameters are estimated with attitude independently from two quantities： the measured magnitude of the Earth’s magnetic field, and the measured dot product of the magnetic field vector and the sun vector. To guarantee the filter’s effectiveness, it is recommended that the sun sensor should at least have the same level of accuracy as magnetometer. Furthermore, to reduce filter’s computation expense, simplification methods in EKF’s Jacobian calculations are introduced and testified, and a polynomial model for fast magnetic field calculation is developed. With these methods, 50% of the computation expense in dynamic model propagation and 80% of the computation burden in measurement model calculation can be reduced. Tested with simulation data and compared with original magnetometer-only methods, filter achieves faster convergence and higher accuracy by 75% and 30% respectively, and the suggested simplification methods are proved to be harmless to filter’s estimation performance.

2018年3月8?9日,中国临床肿瘤学会(Chinese Society of Clinical Oncology,CSCO)和中国抗癌协会肺癌专业委员会联合主办了第15届“中国肺癌高峰论坛”。本次论坛的主题为“聚焦中枢神经系统转移:精确诊断,精准治疗”。晚期肺癌患者往往合并脑转移,在1 000多例的肺癌尸检结果中,肺癌脑转移发生率23%~36%,是脑转移性肿瘤中最常见的类型,且通常预后较差[1]。目前肺癌脑(膜)转移的综合治疗管理和治疗结果,仍不令人满意,治疗效果不佳,中位总生存时间16个月,其中脑膜转移的患者则仅为4.5个月左右[2?5]。近10年肺癌的治疗出现了革命性的改变,但肺癌脑转移的诊断和治疗成了提高肺癌长期生存率的瓶颈。临床医师及科研工作者,应如何对脑转移进行准确及时的诊断?在众多的分型分类体系中,又该如何参考应用?如何全面地对脑转移患者的颅内/颅外病灶进行合理评估?对于伴有驱动基因敏感突变的脑转移患者群体,应怎样对待酪氨酸激酶抑制剂(tyrosine kinase inhibitor,TKI)治疗的定位和应用时机?随着血管生成抑制剂和免疫检查点Checkpoint抑制剂的应用发展,新的治疗选择在肺癌脑转移治疗应用中又该如何管理?以上都是肺癌脑转移综合管理中的疑点和难点,急需解答和形成共识以指导临床实践。本次肺癌高峰论坛,综合近年来发表的前瞻性及回顾性重要研究结果、结合我国肺癌脑转移治疗管理的实际情况,与会专家们就肺癌脑转移的综合管理进行了详细的讨论和各抒己见的争辩,最后达成了以下四点共识。
