Available in PDF, EPUB and Kindle. Book excerpt: "Satellite design, development, fabrication, testing and entry into service is a complex process. Each step of this process involves intricate steps to achieve the desired objective. This thesis summarizes a study relating to the area of development and testing of microsatellites to support qualification and eventually preparing a spacecraft for spaceflight. Students in the Space Systems Engineering laboratory (SSE Lab) in the Aerospace Engineering Program are in the process of developing a pair of microsatellites for a technology demonstration in space. After the initial design of the spacecraft is completed in the design phase a significant amount of time is spent on gaining confidence in the design. Various mathematical models are developed to represent the system and to verify its functionality. In the case of the primary structure of microsatellite a finite element model (FEM) is used to predict the behavior of the satellite structure and to verify strength requirements of design before its fabrication. Finite element model its application and results obtained form the majority of this thesis after which concentration is given to the testing phase of the microsatellite. After gaining confidence in the design and fabrication of the components it is important to validate the structure by subjecting it to structural testing. Structural testing is the only means to gain confidence in the design and certifying it for spaceflight. The results obtained from testing show how closely mathematical model (FEM) represents the physical system and provides an important learning experience for the satellite team and to help better understand and improve the design of the next generation of satellites on campus"--Abstract, leaf iii

Book excerpt: Microsatellite has been considered as disruptive technologies in satellite engineering. Its development cost and time provide advantages for new kind of Earth observations, telecommunications, and science missions. The increasing trend of microsatellite launches and operations means that the approach was so successful that it could create funding sustainability. Major contributing factors of its success were due to the system design of the microsatellites. This chapter discusses two microsatellite system design approaches, namely Technical University of Berlin heritage and University of Surrey heritage. Both Universities provide approaches for system design and build of microsatellite systems. The design approaches are being compared along with lessons learned. The choices of microsatellites to be compared in this chapter will be those that are manufactured about the same time such that the technology compared is mostly the same and flown in-orbit. The chapter shows that the differences between the two system design approaches are on the choice of main computer and associated link configuration and in the attitude control modes. Another major different is in the satellites,Äô structure design. For some satellite,Äôs components, incoming technologies have made the design choices from the two schools of thoughts converged.

Download or read book Integrated Design for Space Transportation System written by B.N. Suresh and published by Springer. This book was released on 2015-11-20 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book addresses the overall integrated design aspects of a space transportation system involving several disciplines like propulsion, vehicle structures, aerodynamics, flight mechanics, navigation, guidance and control systems, stage auxiliary systems, thermal systems etc. and discusses the system approach for design, trade off analysis, system life cycle considerations, important aspects in mission management, the risk assessment, etc. There are several books authored to describe the design aspects of various areas, viz., propulsion, aerodynamics, structures, control, etc., but there is no book which presents space transportation system (STS) design in an integrated manner. This book attempts to fill this gap by addressing systems approach for STS design, highlighting the integrated design aspects, interactions between various subsystems and interdependencies. The main focus is towards the complex integrated design to arrive at an optimum, robust and cost effective space transportation system. The orbital mechanics of satellites including different coordinate frames, orbital perturbations and orbital transfers are explained. For launching the satellites to meet specific mission requirements, viz., payload/orbit, design considerations, giving step by step procedure are briefed. The selection methodology for launch vehicle configuration, its optimum staging and the factors which influence the vehicle performance are summarized. The influence of external, internal and dynamic operating environments experienced by the vehicle subsystems and the remedial measures needed are highlighted. The mission design strategies and their influence on the vehicle design process are elaborated. The various critical aspects of STS subsystems like flight mechanics, propulsion, structures and materials, thermal systems, stage auxiliary systems, navigation, guidance and control and the interdependencies and interactions between them are covered. The design guidelines, complexity of the flight environment and the reentry dynamics for the reentry missions are included. The book is not targeted as a design tool for any particular discipline or subsystem. Some of the design related equations or expressions are not attempted to derive from the first principle as this is beyond the scope of this book. However, the important analytical expressions, graphs and sketches which are essential to provide in-depth understanding for the design process as well as to understand the interactions between different subsystems are appropriately included.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resilient and effective hardware is essential for sustained satellite operation. Any hardware that exists on a satellite must be well designed and undergo rigorous testing to be suitable for space flight. The DEFIANT platform is a microsatellite design that facilitates assembly and integration to shorten the development time of new satellite missions. In this thesis, the design of a wiring harness for the DEFIANT microsatellite platform is presented in detail followed by unit level testing and analysis of two attitude sensors and one attitude actuator. The wiring harness design methodology will be discussed emphasizing the simplistic design for effortless satellite integration and achieving repeatable and consistent assembly results through a straightforward manufacturing process. In addition, various attitude determination and control sensors and actuators present on the DEFIANT platform are tested and analyzed to quantify performance and survivability for operation in space. Throughout this thesis, the author will be assessing the impact on the system level design and assembly of a satellite that stem from unit level hardware designs, or test and analysis results.

This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work deals with the structural design and analysis of the Microvariability of Oscillations of Stars (MOST) microsat mission: Canada's first microsatellite mission and first space telescope. The preliminary study phase of the MOST mission proposes the use of the UoSAT tray stack concept as the primary bus structure. However, due to the size and requirements of the science payload (telescope enclosure), an alternative suitcase size structure (keeping the idea of a tray stack as the spinal bone of the primary structure) is conceptualised. Preliminary finite element analyses included herein highlight certain design weaknesses. Design recommendations are formulated and lead to the critical design of the MOST structure. As the design phases progress, the finite element models are refined, both at the component and at the spacecraft level. In an attempt to minimise the design cost, and following the AMSAT cost-effective philosophy, minimal mechanical testing is planned for the MOST mission. Hence, the spacecraft analysis via finite element methods is used herein to ensure structural reliability. The resulting safety margins, when the worst case load scenario is considered, adds confidence by largely surpassing the potential errors introduced by domain discretization and element formulation. The analyses confirm the MOST structure design to be adequate. Finally, this work presents a detailed engineering analysis leading to the design of the MOST tie rods structural component. The tray stack conceptual design offers great advantages in terms of the ease of assembly. However, the sizing of tie rods for small satellites using a tray stack as a primary structure remains a challenging design problem. This work addresses the issues pertaining to tie rod design, and concludes with the appropriate tie rod design recommendations.

This book was released on 2004-03-01 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of using a microsatellite to accomplish an orbital rendezvous with a noncooperative target was evaluated. This study focused on identifying and further exploring the technical challenges involved in achieving a noncooperative rendezvous. A system engineering analysis and review of past research quickly led to a concentration on the guidance, navigation, and control elements of the microsatellite operation. The integration of control and orbit determination algorithms was investigated. A simple yet robust solution could not be found to meet reasonable rendezvous criteria, using essentially off-the- shelf technology and algorithms. System feasibility has been assessed to have a low probability in the very near term.
