On-orbit operations optimization among multiple cooperative or noncooperative spacecraft, which is often challenged by tight constraints and shifting parameters, has grown to be a hot issue in recent years. The authors of this book summarize related optimization problems into four planning categories: spacecraft multi-mission planning, far-range orbital maneuver planning, proximity relative motion planning and multi-spacecraft coordinated planning. The authors then formulate models, introduce optimization methods, and investigate simulation cases that address problems in these four categories. This text will serve as a quick reference for engineers, graduate students, postgraduates in the fields of optimization research and on-orbit operation mission planning.

Operations Research in Space and Air is a selection of papers reflecting the experience and expertise of international OR consulting companies and academic groups. The global market and competition play a crucial part in the decision making processes within the Space and Air industries and this book gives practical examples of how advanced applications can be used by Space and Air industry management. The material within the book provides both the basic background for the novice modeler and a useful reference for experienced modelers. Students, researchers and OR practitioners will appreciate the details of the modeling techniques, the processes that have been implemented and the computational results that demonstrate the benefits in applying OR in the Space and Airline industries. Advances in PC and Workstations technology, in optimiza tion engines and in modeling techniques now enable solving problems, never before attained by Operations Research. In recent years the Ital ian OR Society (AfRO, www. airo. org) has organized annual forums for researchers and practitioners to meet together to present and dis cuss the various scientific and technical OR achievements. The OR in Space 8 Air session of AfR02001 and AfR02002 Conferences, together with optimization tools' applications, presented recent results achieved by Alenia Spazio S. p. A. (Turin), Alitalia, Milan Polytechnic and Turin Polytechinc. With additional contributions from academia and indus try they have enabled us to capture, in print, today's 'state-of-the-art' optimization and data mining solutions.

Satellites at geosynchronous orbital altitudes are highly valuable for national defense, but are also difficult to access and monitor. Uncrewed inspection spacecraft could supervise various essential defense platforms and deter covert rendezvous by adversaries with malicious intent. 'Neighborhood watch' satellites tasked with this situational awareness mission should be designed and operated in such a way as to maximize their lifespan and efficacy. Motivated by this requirement, this thesis explores the prolonged medium- to close-range spacecraft proximity operations problem from the perspective of continuous optimal trajectory control. A numerical optimization framework is presented for developing and analyzing fuel-, energy-, and time-optimal trajectories with multiple phases using Gauss pseudospectral collocation software. Emphasis is placed on energy efficiency during inspection, for which accurate dynamical models play a critical role in formationkeeping fuel consumption. Various scenarios are analyzed for minimum-energy solutions, such as tactical phasing and insertion into periodic trajectories, avoidance of 'no-fly' zones, inclusion of coupling attitude dynamics, and operations with highly-eccentric targets. This thesis focuses primarily on proximity operations carried out in geosynchronous orbital regimes and neglects orbit perturbations, instead determining the pure cost of linearizing Keplerian gravity using the Hill-Clohessy-Wiltshire model. Error in relative position, angular rate of circumnavigation, and fuel use to enforce linearized periodic trajectories are characterized. It was determined that proximity operations utilizing low-thrust high-specific-impulse solar electric propulsion are well-suited to minimum-energy trajectory optimization with this method. While the contributed analysis tool is not suitable for on-board optimal trajectory generation, it provides a framework to perform useful pre-mission analyses.

This volume presents a selection of advanced case studies that address a substantial range of issues and challenges arising in space engineering. The contributing authors are well-recognized researchers and practitioners in space engineering and in applied optimization. The key mathematical modeling and numerical solution aspects of each application case study are presented in sufficient detail. Classic and more recent space engineering problems – including cargo accommodation and object placement, flight control of satellites, integrated design and trajectory optimization, interplanetary transfers with deep space manoeuvres, low energy transfers, magnetic cleanliness modeling, propulsion system design, sensor system placement, systems engineering, space traffic logistics, and trajectory optimization – are discussed. Novel points of view related to computational global optimization and optimal control, and to multidisciplinary design optimization are also given proper emphasis. A particular attention is paid also to scenarios expected in the context of future interplanetary explorations. Modeling and Optimization in Space Engineering will benefit researchers and practitioners working on space engineering applications. Academics, graduate and post-graduate students in the fields of aerospace and other engineering, applied mathematics, operations research and optimal control will also find the book useful, since it discusses a range of advanced model development and solution techniques and tools in the context of real-world applications and new challenges.

In the work Optimization methodology of hierarchical control of orbit constellations a new approach is proposed to the research of hierarchical optimization problem of large control systems. The unique methods are developed which allow determining the laws of spacecraft optimal control during the different flight stages without the use of complicated calculation procedures of boundary tasks solution. The development of hierarchical principles of optimization is one of the tendencies for methodology improvement of research of control operations in different areas of science and technology. The proposed methodological approach can be widely used in the fields of space navigation, aviation, machine building, monitoring of near earth space, mathematical modelling, optimal control.

The objective of this thesis is to determine a safe-operational orbit corridor of orbit raising of CLIMB satellite mission. CLIMB is the new 3U CubeSat, currently in development at Fachhochschule Wiener Neustadt. The mission goal is to reach the inner Van Allen belt to measure the impact of space radiation on commercial off-the shelf elements. The main objective of this thesis is to access the orbit raising phase during which the CLIMB propagates from an apogee altitude of 500km to an altitude of 1000km, by using thrust manoeuvres at perigee. The assessment also includes technical constraints such as realignments requirements and collision avoidance for safe operation.The first part of thesis explains the concepts behind the tools and methods used during this thesis. The first step includes determining the effective drag area of the CLIMB spacecraft, and an assessment of population flux around the satellite during orbit raising. For the assessment of drag area ESAs CROC tool is used and for assessment of population flux ESAs MASTER tool is used. The next part of thesis deals with theoretical values of conjunctions with collision probability and required manoeuvres obtained using ESAs DRAMA. After evaluation of theoretical conjunction events, strategies to avoid collisions are developed using the IFM FEEP thruster, developed by FOTEC, research center of FHWN. The next part of thesis deals with orbit raising and inclusion of constraints. Various thrust durations and magnitude are used for orbit raising to obtain an orbital corridor containing all the possible values.The final assessment uses Sieves algorithm incorporated in NEPTUNE to perform conjunction assessment with a defined screening volume around the satellite. The conjunction results are then filtered based of screening volumes defined by 18 SPCS, and a plan is presented in order to reduce/avoid thedetermined conjunction events.*****The objective of this thesis is to determine a safe-operational orbit corridor
