Satellite Ground truth Information Fusion (SatGIF)
ABSTRACT: To maintain the most actionable SSA, analysts must assimilate the best available information regarding on-orbit satellite position, orientation, motion, functionality, health, and numerous other parameters to ensure a blue asset is able to perform its mission capably. The availability of ground-truth presents an opportunity to uniquely characterize and fingerprint a satellite based on predictions of its reflective and thermal properties. This fingerprint can then be compared to real-time satellite measurements to more accurately assess current satellite functionality and its impact on mission success. We propose Satellite Ground-truth Information Fusion (SatGIF), a knowledge management system that will provide innovative data visualizations and displays that support the analyst"s mental processes and investigatory methods, providing decision aids and alerting capabilities to increase SSA. Aptima"s SatGIF solution accounts for dynamic user needs (because of expertise, conditions, situations) through development of algorithms and architectures sufficiently nimble to handle a host of data inputs, user inputs, and user expectations. SatGIF will fuse disparate resources; combine space and earth observations with elements of imagery, spectral analysis, and radar returns; coordinate these over time and space; and run models of atmospheric disturbances to reduce uncertainty to support the information seeking and decision-making tasks of the analyst. BENEFIT: The SatGIF solution will help achieve AFRL RV"s objective of improving the reliability and utility of ground-truth data, driving toward a future state in which a vast array of operators will have access to and find benefit for such capabilities. Within the vehicle of the SBIR, Aptima anticipates it can contribute to advancing the current system infrastructure, characterizing human-centered, workflow driven requirements, and developing interactive designs and strategies that will benefit the program. The proposed product is an intelligent, intuitive knowledge management system that pulls data from multiple sources (databases or applications), combines the data into unique visualizations of a predictive nature, and provides rigorous unbiased input to analysts. The system utilizes multifaceted browsing capabilities, context-driven algorithms, pattern matching, and data mining, coupled to satellite/space models, to rapidly provide data-driven recommendations to analysts. It is fully interactive, permitting analysts to test and visualize hypotheses via an intuitive graphical user interface that blends seamlessly with the way they think and work. A rich library of templates for visualizing parameters and interactions between parameters makes it easy to view complex interactions. In addition, advanced computation flow techniques act to order and obtain data required to rapidly complete appropriate visualization(s) and recommendations.
