NASA's COST LESS Team is pursuing strategies to reduce the cost and complexity of planning and executing space missions. The team's technical goal is to reverse the trend of constructing unique solutions for similar problems. To this end, the team is exploring ways to represent mission functionality in terms of building blocks and is discovering approaches that could accommodate the same building blocks for seemingly disparate activities, such as organizing processed telemetry data, controlling onboard experiments, searching science archives, reducing and presenting information to science users, and supporting educational outreach. Reusable object technology (UOT), a research undertaking by the authors, is showing promise in recognizing similarities in functions which were previously viewed as unique because they appeared in different programs or mission phases. Since UOT is aimed at being implementation independent (i.e. the function performed could be accomplished manually, by an automated process, by a specialized instrument, etc.), no premature judgment for automation or autonomy need be made. In this paper, the authors attempt to strike a balance between theory and reality as they describe UOT, including its beginnings, its underpinning, its utility, and its potential for achieving substantive reductions in cost and complexity for the Agency's space programs. The authors discuss their collaboration with the Center for EUV Astrophysics, University of California, Berkeley to reduce the cost and complexity of science investigations. Their multi-disciplinary plan incorporates both UOT and a complementary technology introduced in this paper, called interactive archives.  相似文献

针对深空自主无线电接收技术中信噪比(SNR)未知的载波跟踪问题,提出了一种自适应融合的交互式多模型(IMM)算法,可以根据实际环境的信噪比自适应地调节IMM估计器的噪声方差,以实现对未知SNR信号的正常跟踪,并保证频率跟踪精度几乎不受初始噪声方差的影响。在分析系统收敛性的基础上,该算法采用模型概率自适应调整策略,根据系统收敛判断条件自适应地调整IMM模型集中各模型的概率,保证了系统的收敛性,提高了跟踪精度,与广泛使用的Sage-Husa自适应滤波算法相比,收敛时间缩短了一倍左右。  相似文献

At present, current filters can basically solve the filtering problem in target tracking, but there are still many problems such as too many filtering variants, too many filtering forms, loosely coupled with the target motion model, and so on. To solve the above problems, we carry out crossapplication research of artificial intelligence theory and methods in the field of tracking filters. We firstly analyze the computation graphs of typical a-β and Kalman. Through analysis, it is concluded that ...  相似文献
