Download or read book The Value Proposition of Distributed Satellite Systems for Space Science Missions written by Benjamin Andrew Corbin and published by . This book was released on 2015 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resources available for planetary science missions are finite and subject to some uncertainty. Despite decreasing costs of spacecraft components and launch services, the cost of space science missions is increasing, causing some missions to be canceled or delayed, and fewer science groups have the opportunity to achieve their goals due to budget limits. New methods in systems engineering have been developed to evaluate flexible systems and their sustained lifecycle value, but these methods are not yet employed by space agencies in the early stages of a mission's design. Previous studies of distributed satellite systems (DSS) showed that they are rarely competitive with monolithic systems; however, comparatively little research has focused on how DSS can be used to achieve new, fundamental space science goals that simply cannot be achieved with monolithic systems. The Responsive Systems Comparison (RSC) method combines Multi-Attribute Tradespace Exploration with Epoch-Era Analysis to examine benefits, costs, and flexible options in complex systems over the mission lifecycle. Modifications to the RSC method as it exists in previously published literature were made in order to more accurately characterize how value is derived from space science missions. A tiered structure in multi-attribute utility theory allows attributes of complex systems to be mentally compartmentalized by stakeholders and more explicitly shows synergy between complementary science goals. New metrics help rank designs by the value derived over their entire mission lifecycle and show more accurate cumulative value distributions. A complete list of the emergent capabilities of DSS was defined through the examination of the potential benefits of DSS as well as other science campaigns that leverage multiple assets to achieve their scientific goals. Three distinct categories consisting of seven total unique capabilities related to scientific data sampling and collection were identified and defined. The three broad categories are fundamentally unique, analytically unique, and operationally unique capabilities. This work uses RSC to examine four case studies of DSS missions that achieve new space science goals by leveraging these emergent capabilities. ExoplanetSat leverages shared sampling to conduct observations of necessary frequency and length to detect transiting exoplanets. HOBOCOP leverages simultaneous sampling and stacked sampling to study the Sun in far greater detail than any previous mission. ÆGIR leverages census sampling and self-sampling to catalog asteroids for future ISRU and mining operations. GANGMIR leverages staged sampling with sacrifice sampling and stacked sampling to answer fundamental questions related to the future human exploration of Mars. In all four case studies, RSC showed how scientific value was gained that would. be impossible or unsatisfactory with monolithic systems. Information gained in these studies helped stakeholders more accurately understand the risks and opportunities that arise as a result of the added flexibility in these missions. The wide scope of these case studies demonstrates how RSC can be applied to any science mission, especially one with goals that are more easily achieved with (or impossible to achieve without) DSS. Each study serves as a blueprint for how to conduct a Pre-Phase A study using these methods.

Book excerpt: Distributed Systems: Concurrency and Consistency explores the gray area of distributed systems and draws a map of weak consistency criteria, identifying several families and demonstrating how these may be implemented into a programming language. Unlike their sequential counterparts, distributed systems are much more difficult to design, and are therefore prone to problems. On a large scale, usability reminiscent of sequential consistency, which would provide the same global view to all users, is very expensive or impossible to achieve. This book investigates the best ways to specify the objects that are still possible to implement in these systems.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Current trends in space systems are towards the design of autonomous spacecraft that are capable to generate their own plans of action based on system constraints, on-board data analysis and mission goals set by ground operators. At the same time, the requests in Earth Observation applications has forced the exploration of innovative satellite systems such as satellite swarms, constellations, fully-fractionated spacecraft and federated satellite systems. Enabled by miniaturization techniques and small-spacecraft technologies (e.g. nano-satellites), these distributed mission architectures present improved system qualities (i.e. modularity, scalability, resiliency, incremental deployment...) and performance (e.g. spatial resolution, shorter revisit times...). Although Mission Planning Systems (MPS) for satellites are traditionally ground-based and centralized, providing autonomous capabilities to distributed spacecraft could be the only feasible solution in these new mission architectures where requests are served in a cooperative manner. Regardless of the benefits of autonomous distributed spacecraft, these approaches pose significant challenges in the core component of their planning systems, namely, distributed task schedulers. In this context, this thesis will contribute to the exploration of task schedulers for distributed spacecraft. The purpose of this thesis is twofold: on the one hand to fully design and implement a distributed task scheduling policy. This approach is targeted for the broad range of distributed satellite missions, presenting an adaptive management policy based on the collaboration between two levels of control for dynamic environments with limited computational capabilities. On the other hand the performance of this policy is tested in a simulated environment, against another state-of-the-art alternative, which has been also completely implemented. A benchmark framework has been specifically designed for this purpose. The obtained results have allowed to detect the weaknesses and strengths of this policy and the next steps to be taken in order to have a distributed task scheduler prepared for the future distributed spacecraft architectures.

Download or read book Introduction to Space Systems written by Miguel A. Aguirre and published by Springer Science & Business Media. This book was released on 2012-08-16 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definition of all space systems starts with the establishment of its fundamental parameters: requirements to be fulfilled, overall system and satellite design, analysis and design of the critical elements, developmental approach, cost, and schedule. There are only a few texts covering early design of space systems and none of them has been specifically dedicated to it. Furthermore all existing space engineering books concentrate on analysis. None of them deal with space system synthesis – with the interrelations between all the elements of the space system. Introduction to Space Systems concentrates on understanding the interaction between all the forces, both technical and non-technical, which influence the definition of a space system. This book refers to the entire system: space and ground segments, mission objectives as well as to cost, risk, and mission success probabilities. Introduction to Space Systems is divided into two parts. The first part analyzes the process of space system design in an abstract way. The second part of the book focuses on concrete aspects of the space system design process. It concentrates on interactions between design decisions and uses past design examples to illustrate these interactions. The idea is for the reader to acquire a good insight in what is a good design by analyzing these past designs.
