Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Long-duration Proximity Operations Flexibly Optimized for Efficient Inspection and Servicing Using Free-orbit Dynamics by : Zachary Kahl Funke
Download or read book Long-duration Proximity Operations Flexibly Optimized for Efficient Inspection and Servicing Using Free-orbit Dynamics written by Zachary Kahl Funke and published by . This book was released on 2017 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Rendezvous Optimization and GNC Design for Proximity Operations on Cis-lunar Near Rectilinear Halo Orbits by : Emmanuel Blazquez
Download or read book Rendezvous Optimization and GNC Design for Proximity Operations on Cis-lunar Near Rectilinear Halo Orbits written by Emmanuel Blazquez and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of Human Spaceflight exploration mission scenario, with the Deep Space Gateway (DSG) on a Near Rectilinear Halo Orbit (NRHO) about Earth-Moon Lagrangian Point (EML), Rendezvous and Docking (RVD) operational activities are mandatory and critical for assembly of the DSG to be performed by the Orion spacecraft. Orion will also handle cargo delivery and crew exchange missions and they all require RVD. There is extensive experience with RVD in the two-body problem in Low Earth Orbit to various space stations or around Low Lunar Orbit quasi circular, the latter by Apollo in manual RVD. Despite that no operational RVD has yet been performed in the vicinity of the Lagrangian points, where Keplerian dynamics is not applicable. There are some drawbacks from the complexity, but also some strong advantages that need to be researched in depth by the work proposed here. Despite vast literature on families of trajectories about the Lagrangian points and transfers in the Cis-Lunar realm, the scientific community has, at the moment, very few relevant research results in the non Keplerian dynamic domain. However, in recent years one can be seen the emergence of some sparse publications on the subject, which can be explained by the studies related to DSG and Orion missions. Within the partners, semi-analytical tools have been developed to compute and model families of orbits like NRHO, DRO, Lyapunov, Halo and Lissajous about the Lagrangian points in the Circular Restricted Three Body Problem (CR3BP). Hence there is a good starting point for the research for the overall rendezvous strategy considering vehicle and operations constraints. The proposed PhD project is expected to further and strengthen the work already carried out and some of the celestial mechanics tools developed. Further to that research shall be performed regarding the GNC design for such missions and the accuracies that can be achieved with today technologies and what is required. Assuming the DSG to be the target, RVD will be performed in this project by visiting vehicles arriving from the Earth.

This book was released on 2018-11-02 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide instructs users in the operation of a Proximity Operations Planning System. This system uses an interactive graphical method for planning fuel-efficient rendezvous trajectories in the multi-spacecraft environment of the space station and allows the operator to compose a multi-burn transfer trajectory between orbit initial chaser and target trajectories. The available task time (window) of the mission is predetermined and the maneuver is subject to various operational constraints, such as departure, arrival, spatial, plume impingement, and en route passage constraints. The maneuvers are described in terms of the relative motion experienced in a space station centered coordinate system. Both in-orbital plane as well as out-of-orbital plane maneuvering is considered. A number of visual optimization aids are used for assisting the operator in reaching fuel-efficient solutions. These optimization aids are based on the Primer Vector theory. The visual feedback of trajectory shapes, operational constraints, and optimization functions, provided by user-transparent and continuously active background computations, allows the operator to make fast, iterative design changes that rapidly converge to fuel-efficient solutions. The planning tool is an example of operator-assisted optimization of nonlinear cost functions. Grunwald, Arthur J. and Ellis, Stephen R. Ames Research Center...

Book Synopsis Orbit Assessment and Optimization of CLIMB by : Abhishek Goswami
Download or read book Orbit Assessment and Optimization of CLIMB written by Abhishek Goswami and published by . This book was released on 2021 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
