Information sharing in multinational security and military operations. Why and why not? With whom and with whom not?

Military operations increasingly require cooperation between agencies within the same nation, but also collaboration with security and military organizations internationally. Throughout history multinational military cooperation has often been an appropriate way to conduct major operations; national manpower and material resources are generally insufficient to address the demands of missions worldwide. The desire to optimize the use of scarce research and development and investment capabilities, the need for international legitimacy and political support, and the fact that today’s risks transcend national borders, have rendered multinational cooperation in the security domain unavoidable. With joint operations comes the requirement for multi-partner- and multinational information sharing. However, information sharing has both advantages and costs, and is subject to both enabling factors as well as barriers. This paper reflects on theories, both classical and current, as well as empirical case studies, to examine the pros and cons of multinational information sharing, and the factors that conduce or interfere with the transmission and the receipt of intelligence. The importance of a holistic approach and of learning lessons learned are two key lessons gleaned from the analysis, along with an emphasis on developing both the organizational and the interpersonal enablers of information sharing.     

基于星间链路GNSS自主完好性加权算法

全球卫星导航系统在自主导航工作模式下,传统的地面支持完好性系统无法满足用户的完好性要求。因此提出一种基于星间链路的全球卫星导航系统(GNSS)自主完好性加权算法,通过改进稳健估计理论中的M-估计对星间链路测距加权的计算方法,降低故障卫星星间测距值的影响,以保持星座自主时间同步和精密定轨处理的连续、稳定与精度。仿真结果表明,在一颗及两颗故障卫星情况下,基于星间链路的GNSS自主完好性加权算法,可以有效地消除故障卫星对自主导航精密定轨的影响,星座具有与无故障时相当的自主定轨精度。

空间双体系绳系统展开阶段末端星姿态动力学分析

为了研究空间系绳系统展开过程中末端星的姿态运动,采用第二类拉格朗日方程建立系统展开及末端星角运动的数学模型,分析展开阶段末端星的姿态动力学特性。建模时将系绳末端连接的母星与子星视为尺寸不可忽略的刚体,且母星质量远大于子星质量,系绳视为有质量的刚性杆。利用该数学模型可以分析系绳系统的展开过程,研究影响末端星姿态运动的主要因素,包括姿态角初始扰动以及末端星动/静不对称性。仿真结果表明,系绳展开时末端星姿态角初始扰动及动静不对称性可能会导致姿态角失稳,出现系绳缠绕星体的情况。仿真结果可以为展开阶段末端星姿态控制提供参考。     

基于Hankel范数近似的磁悬浮控制系统模型降阶

对于磁悬浮系统而言,忽略轨道的弹性进行控制算法设计,是一种常见的方法。但是,当轨道的刚度较小时,这种方法的控制性能较差。考虑轨道弹性所设计的控制算法,理论上能确保系统的良好性能但是会使得系统复杂度增加。本文采用Hankel范数近似法对基于弹性轨道的模型进行降阶。针对刚性轨道系统模型和降阶模型设计控制算法,利用仿真结果验证降阶模型的可行性。
